Charging and Discharging of a Capacitor | RC Circuit
When connected to a battery, the capacitor stores electrostatic energy. This energy is in the form of charge on its plates which raises the potential difference between the plates. When required, this capacitor can release this stored energy and gets discharged. A capacitor is charged by connecting it to a voltage source and a resistor.

Understanding DC Circuit Capacitor Behavior
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. Still, where there is a safety issue, larger values might need a discharge (bleed) resistor to control the current value during discharge.

Capacitor Charging and Discharging Equation and RC Time …
A discharged capacitor behaves like a short circuit when initially connected to the circuit, which means causing a surge current initially. A capacitor behaves like an open circuit when it is fully charged, which means not allowing current through it. In the discharging phase, the voltage and current both exponentially decay down to zero.

safety
Furthermore, if you accidentally connect the ground terminal of the capacitor to the metal case, the capacitor will not discharge. Because of this, it is a good idea to discharge all capacitors by connecting the terminals together (either with a conductive material or a resistor) until the capacitor is discharged. (You can check with a ...

Why is a capacitor considered a short circuit at start up?
In the case where a DC voltage is applied to a capacitor we are assuming that the capacitor has been previously discharged. The voltage across a capacitor can not change instantaneously so the initial voltage across the capacitor is 0. The capacitor then charges to the value of the input voltage and current stops flowing. Under this steady ...
