21.6: DC Circuits Containing Resistors and Capacitors

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.
