As the capacitor discharges, the stored charge decreases, causing a gradual drop in voltage across the capacitor and an exponential decrease in the discharge current. As a result, the brightness of the green LED quickly dims and eventually goes out.
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.

In storing charge, capacitors also store potential energy, which is equal to the work (W) required to charge them. For a capacitor with plates holding charges of +q and -q, this can be calculated: (mathrm { W } _ { mathrm { stored } } = frac { mathrm { CV } ^ { 2 } } { 2 }). The above can be equated with the work required to charge the ...
