Electric circuits can be described in a variety of ways. An electric circuit is commonly described with mere words like A light bulb is connected to a D-cell . Another means of describing a circuit is to simply draw it. A final means of describing an electric circuit is by use of conventional circuit symbols to provide a schematic diagram of the circuit and its components.
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.
