Discharging a Capacitor Definition: Discharging a capacitor is defined as releasing the stored electrical charge within the capacitor. Circuit Setup: A charged capacitor is connected in series with a resistor, and the circuit is short-circuited by a switch to start discharging.
Discharging a capacitor means releasing the stored electrical charge. Let’s look at an example of how a capacitor discharges. We connect a charged capacitor with a capacitance of C farads in series with a resistor of resistance R ohms. We then short-circuit this series combination by closing the switch.
Voltages parallel to a capacitor may also be found when there is no flow of current. (iii). A capacitor has a capacity to store charge. (iv). It has become clear from i = C dv / dt that a current in a capacitor exists at a time when voltages found parallel to it, change with the time.

For the last question, it is possible to discharge the capacitor by directly shorting it without blow up the cap. This is one of the safety demo my professor love to do. He will touch the two ends of a cap (which is the size of a bottle) with a metal rod. You will see a huge bright arc at the contact and a huge sound (worse then firing a gun).
The charge of a capacitor is directly proportional to the area of the plates, permittivity of the dielectric material between the plates and it is inversely proportional to the separation distance between the plates.

Summary Capacitors are energy storage devices. An ideal capacitor act like an open circuit at steady state when a DC voltage or current has been applied. The voltage across a capacitor must be a continuous function; the current flowing through a capacitor can be discontinuous. t dvC iC = C dt 1 1 vC = ∫ iC dt C to The equations for equivalent capacitance …
