How to Safely Discharge a Capacitor | DigiKey
Another way to discharge a capacitor would be to source an incandescent light bulb that can tolerate the voltage held in the capacitor. Hook this up and once the bulb is no longer lit, the capacitor is discharged. Again, you always want to measure the voltage after it''s supposedly discharged just to be safe. For a visual demonstration on this ...

Will a charged capacitor discharge if one lead is connected to ground?
In a charged capacitor, let''s say the potential of one plate (call it A) is different from that of the ground (relative to an arbitrary point). If I connect the plate to the ground, plate+ground will have identical potential, different than the potential of the plate before it was connected to the ground.

Grounding a capacitor involves connecting one of its terminals to the ground or earth. This is typically done using a wire. The ground serves as a reference point and helps to stabilize the voltage across the capacitor. It also provides a path for the discharge of the stored energy in the capacitor, which can be important for safety reasons.

Two concepts that you are missing: "ground" is arbitrary and voltage is relative. And one more: current flows in loops. In the first example, R2 is shorted by SW1. This also shorts the capacitors right plate to ground. You flip SW1 up. this shorts the capacitor and it discharges to zero instantly. All is well.

How to Discharge a Capacitor?
(1) After the capacitor is disconnected from the bus, it must be discharged through a discharge resistor or a special voltage transformer. (2) Discharge between the lead wires of the capacitor and between the lead wires and the casing. (3) The capacitor can be grounded after the capacitor is discharged.

CHARGE AND DISCHARGE OF A CAPACITOR
An electrical example of exponential decay is that of the discharge of a capacitor through a resistor. A capacitor stores charge, and the voltage V across the capacitor is proportional to the charge q stored, given by the relationship. V = q/C, where C is called the capacitance.

Large Capacitor Hazards. Capacitors may store hazardous energy even after the equipment has been de-energized, and may build up a dangerous residual charge without an external source. "Grounding" capacitors in series, for example, may transfer (rather than discharge) the stored energy. Another hazard exists when a capacitor is subjected to high ...
