Understanding Capacitors

Once fully charged, the capacitor blocks the flow of direct current, acting as an open circuit. They act like a temporary storage device and hold this charge indefinitely as long as the supply voltage is present. Thus a capacitors charging current can be defined as: i = CdV/dt. It is important to note that capacitors in DC circuits do not have the continuous charging and discharging …

Understanding DC Circuit Capacitor Behavior

A capacitor is charged up to 200–500 V and discharged into a xenon gas–filled tube. Before handling capacitors or working on circuits where capacitors are used, it is a sensible precaution to ensure they have been discharged. Small capacitors can be discharged directly with a short circuit.
