			The definition of Gauss’s Law is presented clearly, but students would benefit from more examples demonstrating when the law is actually useful. Adding symmetry cases—sphere, cylinder, and infinite plane—would greatly improve the page. A step-by-step field calculation and a simple public-domain diagram would bring this page closer to the template requirements. — Azan Khan, Fall 2025

	Torque is a Latin word that roughly means "twist," and is usually symbolized by the lower case Greek letter tau. Torque is the measurement of how much a force, F, acting on an object will cause that object to rotate. This force is usually applied to an arm of some sort that is attached to a fulcrum or pivot point. For example, using a wrench to loosen or tighten a nut requires the use of torque - where the wrench would be the arm you apply the force to and the nut would be the pivot point that the force rotates around.

			Circuit Elements

			In terms of physics, an electrical circuit is a system which is composed of certain combinations of circuit elements, including resistors, capacitors, and inductors. When used in different combinations, these elements create R, LC, RL, RC circuits. The elements that make up these circuits include capacitors, resistors, batteries, ammeters, voltmeters, ohmmeters. When an electric field is applied to a conductor, the mobile charges in the conductor experience forces, and to move in the direction of those forces. Active circuits do not experience equilibrium, rather they experience a steady state in which means that charges are moving, but their drift velocities do not change with time. For circuits, equilibriums means that there is no current flowing.

			The Main Idea
			To create an active circuit there must be a specific combination of the elements above as well as a nonzero electric field in the wires. The direction of the electric field at every location must be along the wire since the current flow follows the wire. According to the loop rule, energy must be conserved along any closed path in a circuit. Although, using resistors, capacitors, ammeters, voltmeters, ohmmeters, and batteries the flow of current can change with time.

			A Mathematical Model
			In the steady state the net electron current can be shown in the equation:
			i=nAuE

			the conventional current can be solved for through the equation:
			I=\|q\|nAuE

			Energy conservation (the loop rule):
			Net change in potential=0

			Circuits provide the world with many conveniences. From simple circuits within flashlights to parallel circuits in household lighting everyday life is made simpler because of their existence. The difference between parallel and series circuits can be noted through the reaction of Christmas lights to a bulb burning out. If a bulb burns out in a series circuit the entire string of lights will burn out as well. This is because in a series circuit there is only one pathway for the current to flow. When the pathway is disrupted the current is in equilibrium and stops flowing. On the other hand, if a bulb burns out and the remaining bulbs stay lit you know they are connected through a parallel circuit. When the bulbs are connected in parallel there are multiple alternate pathways for the currents to travel in.

			Many careers necessitate an in-depth knowledge of circuits. For the major of mechanical engineering a knowledge of circuits is beneficial for multiple applications. When designing electronic technologies it is necessary to understand the circuitry within the design.


			History
			Early investigations of static electricity go back hundreds of years. Static electricity is a transfer of electrons produced by friction, like when you rub a balloon across a sweater. A spark or very brief flow of current can occur when charged objects come into contact, but there is no continuous flow of current. In the absence of a continuous current, there is no useful application of electricity.
			The invention of the battery -- which could produce a continuous flow of current -- made possible the development of the first electric circuits. Alessandro Volta invented the first battery, the voltaic pile, in 1800. The very first circuits used a battery and electrodes immersed in a container of water. The flow of current through the water produced hydrogen and oxygen.
			The first widespread application of electric circuits for practical use was for electric lighting. Shortly after Thomas Edison invented his incandescent light bulb, he sought practical applications for it by developing an entire power generation and distribution system. The first such system in the United States was the Pearl Street Station in downtown Manhattan. It provided a few square blocks of the city with electric power, primarily for illumination.
			One classification of circuits has to do with the nature of the current flow. The earliest circuits were battery-powered, which made in a steady, constant current that always flowed in the same direction. This is direct current, or DC. The use of DC continued through the time of the first electric power systems. A major problem with the DC system was that power stations could serve an area of only about a square mile because of power loss in the wires.
			In 1883, engineers proposed harnessing the tremendous hydroelectric power potential of Niagara Falls to supply the needs of Buffalo, N.Y. Although this power would ultimately go beyond Buffalo to New York City and even farther, there was an initial problem with distance. Buffalo was only 16 miles from Niagara Falls, but the idea was unworkable -- until Nikola Tesla made it possible, as we'll see on the next page.
