Capacitor discharges the power supply

How to Discharge a Capacitor? Using Bleeder Resistor,

When we connect a DC Power Supply across the leads of a capacitor, the capacitor gradually accumulates charge between its plates until the voltage is equal to the supply voltage. Even if we disconnect the power supply, the capacitor continues to store the charge and in this way, a capacitor acts like a small battery.

RC Discharging Circuit Tutorial & RC Time Constant

As the capacitor discharges, it does not lose its charge at a constant rate. At the start of the discharging process, the initial conditions of the circuit are: t = 0, i = 0 and q = Q. The voltage across the capacitors plates is equal to the supply voltage and V C = V S. As the voltage at t = 0 across the capacitors plates is at its highest
