A capacitor discharges by releasing stored electrical energy. The rate of discharge is affected by factors such as the capacitance of the capacitor, the resistance of the circuit, and the voltage across the capacitor. A higher capacitance or lower resistance will result in a slower discharge rate, while a higher voltage will lead to a faster discharge.
The capacitor can discharge over the connecting wires; i.e., outside the capacitor. Some discharge can also occur over the dielectric, since it will not insulate completely.
For part of the AC voltage wave, the capacitor will be above the source voltage, and will discharge until the AC voltage wave increases above the capacitor's stored voltage.
if the source is switched off there will be leakage slowly discharging the capacitor
Capacitor discharge ignition
Capacitor discharge ignition
A capacitor discharges when it releases the stored electrical energy it has accumulated. This typically happens when the capacitor is connected to a circuit or load that allows the energy to flow out of the capacitor.
When a capacitor is powered off in an energized circuit, the capacitor still stores a certain amount of electricity. When there are other loads or components in the circuit, they will slowly discharge, or they can be quickly discharged by short-circuiting with small resistors or wires (at low voltage). When the capacitor discharges, the two poles of the capacitor respectively carry a certain amount of charge, and the outside world and the capacitor form a closed loop (generally, the closed loop does not include a power supply). The excess electrons (negative charges) approach the positive electrode of the capacitor to form a current, so that the charges at both ends of the capacitor are neutralized. When the neutralization is completed, the electric field between the two electrodes of the capacitor disappears. However, this is in an ideal situation. The amount of terminal charge is exponentially neutralized towards zero, but not zero. Discharge requirements of capacitors After the capacitor is disconnected from the bus, it must be discharged through a discharge resistor or a special voltage transformer. Discharge should be performed between the lead wires of the capacitor and between the lead wires and the casing. The capacitor can be grounded after the capacitor is discharged. Before working on the capacitor, be sure to conduct a test discharge. This discharge is to place the discharge rod on the terminal of the lead wire of the capacitor for a period of time. Even if both sides of the capacitor device are grounded, in order to prevent residual charge on the capacitor, a test discharge must be performed, and each group of capacitors connected in parallel must be discharged. Special care should be taken when conducting inspection discharge of capacitors removed due to faults. Due to the damaged capacitor, the general grounding device may not function as a ground discharge due to a partial disconnection. If the capacitor device has an interlock device, it should be considered that only after the entire device is grounded, the small door of the capacitor bank protective fence can be opened.

Stick a screwdriver between the 2 wires. This discharges the capacitor
If the resistance is in series with the capacitor, the charge/discharge time is extended.
Either the electrolyte leaks out or it develops a short across the plates.
When a capacitor discharges the discharge current flows in the opposite direction to the current used to charge it.
