Short Description of Topic
The Main Idea
Now that we have an understanding of steady state current, we can begin to examine the current in a RC circuit.
The current in a RC circuit differs from the current in a simple circuit because the capacitor acquires and releases charge; this varies the current.
This a graphical representation of the changing current and voltage on a capacitor with respect to time.
A Mathematical Model
The graph presented in the previous section is representative of a exponential equation. The current across a capacitor falls of like [math]\displaystyle{ I = {\frac{emf}{R}}e^{frac{-t}{RC}} }[/math] where p is the momentum of the system and F is the net force from the surroundings.
