<p>Kdobson6: </p> <hr /> <div>CLAIMED BY: Kelsey Dobson<br /> 12/5/2015<br /> <br /> An LC circuit contains an inductor and a capacitor, and because of the inductor's sluggishness and resistance to change the current, the charge in this circuit can oscillate back and forth forever.<br /> <br /> ==The Main Idea==<br /> <br /> A circuit containing an inductor "L" and a capacitor "C" is called an LC circuit. This circuit can oscillate continuously if the resistance is small. Accordingly, the connecting wires in an LC circuit are low-resistance thick copper wires. Here is the basic idea behind the process of an LC circuit:<br /> <br /> A capacitor is charged initially, and then a switch is closed. This connects the capacitor to the inductor. At first, because of the nature of an inductor, it is difficult for charge on the capacitor to flow through the inductor. This is because the inductor opposes all attempts to change the current. However, since an inductor cannot completely prevent a current from changing, there is more current little by little. This drains the capacitor of its charge. <br /> <br /> At the moment the capacitor runs out of charge, there is a current in the inductor, and because inductors are sluggish by nature, the current can't immediately change to zero. Therefore, the system does not come to equililbrium and instead increases the charge in the capacitor. When the capacitor is fully charged, it starts to discharge back through the inductor, and the process repeats. Since the circuit will never reach equilibrium and current never reaches zero, this oscillating process repeats forever. Oscillations could reach a stopping point if there is some resistance, but it may still go through multiple cycles before equilibrium is reached.<br /> <br /> ===A Mathematical Model===<br /> <br /> An LC circuit has an energy conservation rule associated with it. The energy conservation loop rule for an LC circuit is:<br /> <math> \Delta V_{capacitor} + \Delta V_{inductor} = \frac{1}{C}-L\frac{dI}{dt} = 0 </math> where <math>Q</math> is the charge on the upper plate of the capacitor and <math>I</math> is the conventional current leaving the upper plate and going through the inductor.<br /> <br /> <math>dQ/dt</math> is the amount of charge flowing off the capacitor every second. This is the same as the current. Because the charge is leaving the capacitor, <math> I = -\frac{dQ}{dt}</math>.<br /> <br /> Energy conservation can be re-written as <math>\frac{1}{C}Q+L\frac{d^{2}Q}{dt^{2}} = 0 </math><br /> <br /> In addition, by substituting Q and its second derivative into the equation, a possible solution of the rewritten energy conservation equation is <math> Q = Q_{i}cos(\frac{1}{\sqrt{LC}}t) </math><br /> <br /> Therefore, the current is given by: <math> I = -\frac{dQ}{dt} = \frac{Q_{i}}{\sqrt{LC}}sin(\frac{1}{\sqrt{LC}}t) </math><br /> <br /> ===A Computational Model===<br /> <br /> [[File:LCcircuit.jpg]]<br /> <br /> [[File:Tuned_circuit_animation_3_300ms.gif]]<br /> <br /> ==Connectedness==<br /> <br /> This topic is connected to RC circuits, which approach equilibrium slowly, as well as RL circuits, which approach steady state current slowly. However, an LC circuit is an example of a circuit that oscillates, where charge moves back and forth forever, and never settles to an equilibrium or steady state. <br /> <br /> As an engineer, these circuits can be useful in many areas, particularly to electrical and mechanical engineers.

He concluded that this was due to a damped oscillating discharge current in the wire, which reversed the magnetization of the needle back and forth until it was too small to have an effect, leaving the needle magnetized in a random direction.<br /> <br /> == See also ==<br /> <br /> ===External links===<br /> Helpful websites for furthering your understanding of LC circuits, including some mathematical applications:<br /> [http://farside.ph.utexas.edu/teaching/315/Waves/node5.html]<br /> [http://physics.info/circuits-rlc/]<br /> <br /> A helpful video for further information:<br /> [https://www.youtube.com/watch?v=v3-HwZMThzQ]<br /> <br /> ==References==<br /> <br /> Matter & Interactions 4th Edition: Electric and Magnetic Interactions<br /> <br /> http://www.chegg.com/homework-help/questions-and-answers/x-i5rong-please-help-part-g-learning-goal-understand-processes-series-circuit-containing-i-q74127<br /> <br /> https://en.wikipedia.org/wiki/LC_circuit<br /> <br /> http://farside.ph.utexas.edu/teaching/315/Waves/node5.html<br /> <br /> http://physics.info/circuits-rlc/<br /> <br /> https://www.youtube.com/watch?v=v3-HwZMThzQ<br /> <br /> <br /> [[Category:Which Category did you place this in?]]</div>

<p>Kdobson6: /* A Computational Model */</p> <hr /> <div>CLAIMED BY: Kelsey Dobson<br /> 12/5/2015<br /> <br /> An LC circuit contains an inductor and a capacitor, and because of the inductor's sluggishness and resistance to change the current, the charge in this circuit can oscillate back and forth forever.<br /> <br /> ==The Main Idea==<br /> <br /> A circuit containing an inductor "L" and a capacitor "C" is called an LC circuit. This circuit can oscillate continuously if the resistance is small. Accordingly, the connecting wires in an LC circuit are low-resistance thick copper wires. Here is the basic idea behind the process of an LC circuit:<br /> <br /> A capacitor is charged initially, and then a switch is closed. This connects the capacitor to the inductor. At first, because of the nature of an inductor, it is difficult for charge on the capacitor to flow through the inductor. This is because the inductor opposes all attempts to change the current. However, since an inductor cannot completely prevent a current from changing, there is more current little by little. This drains the capacitor of its charge. <br /> <br /> At the moment the capacitor runs out of charge, there is a current in the inductor, and because inductors are sluggish by nature, the current can't immediately change to zero. Therefore, the system does not come to equililbrium and instead increases the charge in the capacitor. When the capacitor is fully charged, it starts to discharge back through the inductor, and the process repeats. Since the circuit will never reach equilibrium and current never reaches zero, this oscillating process repeats forever. Oscillations could reach a stopping point if there is some resistance, but it may still go through multiple cycles before equilibrium is reached.<br /> <br /> ===A Mathematical Model===<br /> <br /> An LC circuit has an energy conservation rule associated with it. The energy conservation loop rule for an LC circuit is:<br /> <math> \Delta V_{capacitor} + \Delta V_{inductor} = \frac{1}{C}-L\frac{dI}{dt} = 0 </math> where <math>Q</math> is the charge on the upper plate of the capacitor and <math>I</math> is the conventional current leaving the upper plate and going through the inductor.<br /> <br /> <math>dQ/dt</math> is the amount of charge flowing off the capacitor every second. This is the same as the current. Because the charge is leaving the capacitor, <math> I = -\frac{dQ}{dt}</math>.<br /> <br /> Energy conservation can be re-written as <math>\frac{1}{C}Q+L\frac{d^{2}Q}{dt^{2}} = 0 </math><br /> <br /> In addition, by substituting Q and its second derivative into the equation, a possible solution of the rewritten energy conservation equation is <math> Q = Q_{i}cos(\frac{1}{\sqrt{LC}}t) </math><br /> <br /> Therefore, the current is given by: <math> I = -\frac{dQ}{dt} = \frac{Q_{i}}{\sqrt{LC}}sin(\frac{1}{\sqrt{LC}}t) </math><br /> <br /> ===A Computational Model===<br /> <br /> [[File:LCcircuit.jpg]]<br /> <br /> [[File:Tuned_circuit_animation_3_300ms.gif]]<br /> <br /> ==Examples==<br /> <br /> Be sure to show all steps in your solution and include diagrams whenever possible<br /> <br /> ===Simple===<br /> ===Middling===<br /> ===Difficult===<br /> <br /> ==Connectedness==<br /> #How is this topic connected to something that you are interested in?<br /> #How is it connected to your major?<br /> #Is there an interesting industrial application?<br /> <br /> ==History==<br /> <br /> Put this idea in historical context.

<p>Kdobson6: /* A Mathematical Model */</p> <hr /> <div>CLAIMED BY: Kelsey Dobson<br /> 12/5/2015<br /> <br /> An LC circuit contains an inductor and a capacitor, and because of the inductor's sluggishness and resistance to change the current, the charge in this circuit can oscillate back and forth forever.<br /> <br /> ==The Main Idea==<br /> <br /> A circuit containing an inductor "L" and a capacitor "C" is called an LC circuit. This circuit can oscillate continuously if the resistance is small. Accordingly, the connecting wires in an LC circuit are low-resistance thick copper wires. Here is the basic idea behind the process of an LC circuit:<br /> <br /> A capacitor is charged initially, and then a switch is closed. This connects the capacitor to the inductor. At first, because of the nature of an inductor, it is difficult for charge on the capacitor to flow through the inductor. This is because the inductor opposes all attempts to change the current. However, since an inductor cannot completely prevent a current from changing, there is more current little by little. This drains the capacitor of its charge. <br /> <br /> At the moment the capacitor runs out of charge, there is a current in the inductor, and because inductors are sluggish by nature, the current can't immediately change to zero. Therefore, the system does not come to equililbrium and instead increases the charge in the capacitor. When the capacitor is fully charged, it starts to discharge back through the inductor, and the process repeats. Since the circuit will never reach equilibrium and current never reaches zero, this oscillating process repeats forever. Oscillations could reach a stopping point if there is some resistance, but it may still go through multiple cycles before equilibrium is reached.<br /> <br /> ===A Mathematical Model===<br /> <br /> An LC circuit has an energy conservation rule associated with it.

<br /> ===Collisions===<br /> <div class="mw-collapsible-content"><br /> [[File:opener.png]]<br /> <br /> *[[Collisions]] <br /> Collisions are events that happen very frequently in our day-to-day world. In the realm of Physics, a collision is defined as any sort of process in which before and after a short time interval there is little interaction, but during that short time interval there are large interactions. When looking at collisions, it is first important to understand two very important principles: the Momentum Principle and the Energy Principle. Both principles serve use when talking of collisions because they provide a way in which to analyze these collisions. Collisions themselves can be categorized into 3 main different types: elastic collisions, inelastic collisions, maximally inelastic collisions. All 3 collisions will get touched on in more detail further on.<br /> [[File:pe.png]]<br /> <br /> *[[Elastic Collisions]]<br /> A collision is deemed "elastic" when the internal energy of the objects in the system does not change (in other words, change in internal energy equals 0). Because in an elastic collision no kinetic energy is converted over to internal energy, in any elastic collision Kfinal always equals Kinitial.<br /> [[File:Elco.png]]<br /> <br /> *[[Inelastic Collisions]]<br /> A collision is said to be "inelastic" when it is not elastic; therefore, an inelastic collision is an interaction in which some change in internal energy occurs between the colliding objects (in other words, change in internal energy does not equal 0). Examples of such changes that occur between colliding objects include, but are not limited to, things like they get hot, or they vibrate/rotate, or they deform. Because some of the kinetic energy is converted to internal energy during an inelastic collision, Kfinal does not equal Kinitial.<br /> There are a few characteristics that one can search for when identifying inelasticity. These indications include things such as:<br /> *Objects stick together after the collision<br /> *An object is in an excited state after the collision<br /> *An object becomes deformed after the collision<br /> *The objects become hotter after the collision<br /> *There exists more vibration or rotation after the collision<br /> [[File:inve.gif]]<br /> <br /> <br /> *[[Maximally Inelastic Collision]] <br /> Maximally inelastic collisions, also known as "sticking collisions", are the most extreme kinds of inelastic collisions. Just as its secondary name implies, a maximally inelastic collision is one in which the colliding objects stick together creating maximum dissipation. This does not automatically mean that the colliding objects stop dead because the law of conservation of momentum. In a maximally inelastic collision, the remaining kinetic energy is present only because total momentum can't change and must be conserved.<br /> [[File:inel.gif]]<br /> <br /> *[[Head-on Collision of Equal Masses]]<br /> The easiest way to understand this phenomenon is to look at it through an example. In this case, we can analyze it through the common game of billiards. Taking the two, equally massed billiard balls as the system, we can neglect the small frictional force exerted on the balls by the billiard table. The Momentum Principle states that in this head-on collision of billiard balls the total final momentum in the x direction must equal the total initial momentum. However, this alone does not give us the knowledge to know how the momentum will be divided up between the two balls. Considering the law of conservation of energy, we can more accurately depict what will happen. This will also allow for one to identify what kind of collision occurs (elastic, inelastic, or maximally inelastic). It is important to know that head-on collisions of equal masses do not have a definite type of collision associated with it.<br /> [[File:momentum-real-life-applications-2895.jpg]] [[File:8ball.gif]]<br /> <br /> *[[Head-on Collision of Unequal Masses]]<br /> Just as with head-on collisions of equal masses, it is easy to understand head-on collisions of unequal masses by viewing it through an example. Let's take for example two balls of unequal masses like a ping-pong ball and a bowling ball. For the purpose of this example (so as to allow for no friction and no other significant external forces), let's imagine these objects collide in outer space inside an orbiting spacecraft. If there were to be a collision between the two, what would one expect to happen? One could expect to see the ping-pong ball collide with the bowling ball and bounce straight back with a very small change of speed. What one might not expect as much is that the bowling ball also moves, just very slowly. Again, this can all be explained through the conservation of momentum and the conservation of energy.<br /> [[File:mi3e.jpg]]<br /> <br /> *[[Frame of Reference]]<br /> In the world of Physics, a frame of reference is the perspective from which a system is observed. It can be stationary or sometimes it can even be moving at a constant velocity. In some rare cases, the frame of reference moves at an nonconstant velocity and is deemed "noninertial" meaning the basic laws of physics do not apply. Continuing with the trend of examples, pretend you are at a train station observing trains as they pass by. From your stationary frame of reference, you observe that the passenger on the train is moving at the same velocity as the train. However, from a moving frame of reference, say from the eyes of the train conductor, he would view the train passengers as "anchored" to the train.<br /> [[File:train.png]]<br /> <br /> *[[Scattering: Collisions in 2D and 3D]]<br /> Experiments that involve scattering are often used to study the structure and behavior of atoms, nuclei, as well as of other small particles. In an experiment like such, a beam of particles collides with other particles. If it is an atomic or nuclear collision, we are unable to observe the curving trajectories inside the tiny region of interaction. Instead, we can only truly observe the trajectories before and after the collision. This is only possible because the particles are at a farther distance apart and have a very weak mutual interaction; this essentially means that the particles are moving almost in a straight line. A good example which demonstrates scattering is the collision between an alpha particle (the nucleus of a helium atom) and the nucleus of a gold atom. One will understand this phenomenon more in depth after first understanding the Rutherford Experiment which will get touched on later.<br /> <br /> *[[Rutherford Experiment and Atomic Collisions]]<br /> In England in 1911, a famous experiment was performed by a group of scientists led by Mr. Ernest Rutherford. This experiment, later known as "The Rutherford Experiment", was a tremendous breakthrough for its time because it led to the discovery of the nucleus inside the atom. Rutherford's experiment involved the scattering of a high-speed alpha particle (now known as a helium nuclei - 2 protons and 2 neutrons) as it was shot at a thin gold foil (consisting of a nuclei with 79 protons and 118 neutrons). In the experiment, Rutherford and his team discovered that the velocity of the alpha particles was not high enough to allow the particles to make actual contact with the gold nucleus. Although they never actually made contact, it is still deemed a collision because there exists a sizable force between the alpha particle and the gold nucleus over a very short period of time. In conclusion, we say the alpha particle is "scattered" by its interaction with the nucleus of a gold atom and experiments like such are called "scattering" experiments.<br /> [[File:ruthef.jpg]]<br /> <br /> *[[Coefficient of Restitution]]<br /> The coefficient of restitution is a measure of the elasticity in a collision. It is the ratio of the differences in velocities before and after the collision. The coefficient is evaluated by taking the difference in the velocities of the colliding objects after the collision and dividing by the difference in the velocities of the colliding objects before the collision.<br /> <br /> <br /> <br /> All of the following information was collected from the Matter and Interactions 4th Edition physics textbook.
