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 …
How to Safely Discharge a Capacitor
When enough time has passed, remove the resistor and re-measure the voltage. At this point it should have achieved the safety threshold voltage. If not, replace the resistor and let it sit for a while longer. Another way to discharge a capacitor would be to source an incandescent light bulb that can tolerate the voltage held in the capacitor.
capacitor
The black line labeled "Waveform with capacitor" shows the capacitor being charged up at the peak of the half-cycle, then draining slowly due to the load once the diodes turn off. A higher capacitance means the capacitor (output) voltage drains more slowly: $$frac {dV_{Capacitor}} {dt} = frac {I_{Load}} {C}$$
