RC Circuits. An (RC) circuit is one containing a resisto r (R) and capacitor (C). The capacitor is an electrical component that stores electric charge. Figure shows a simple (RC) circuit that employs a DC (direct current) voltage source. The capacitor is initially uncharged. As soon as the switch is closed, current flows to and from the initially uncharged capacitor.
The capacitance of a capacitor can be defined as the ratio of the amount of maximum charge (Q) that a capacitor can store to the applied voltage (V). V = C Q. Q = C V. So the amount of charge on a capacitor can be determined using the above-mentioned formula. Capacitors charges in a predictable way, and it takes time for the capacitor to charge.
A capacitor is a device which stores electric charge. Capacitors vary in shape and size, but the basic configuration is two conductors carrying equal but opposite charges (Figure 5.1.1).

After reaching its maximum (I_0), the current i(t) continues to transport charge between the capacitor plates, thereby recharging the capacitor. Since the inductor resists a change in current, current continues to flow, even though the capacitor is discharged. This continued current causes the capacitor to charge with opposite polarity.
