Energy Stored on a Capacitor
From the definition of voltage as the energy per unit charge, one might expect that the energy stored on this ideal capacitor would be just QV. That is, all the work done on the charge in moving it from one plate to the other would appear as energy stored. But in fact, the expression above shows that just half of that work appears as energy stored in the capacitor.

6 FAQs about [Energy storage capacitor grounding]
How do you ground a capacitor?
Clearly mark grounding points and use caution to prevent transferring charges to other capacitors. All grounding hooks must: Have crimped and soldered conductors. Be connected such that impedance is less than 0.1 (omega) to the ground. Have the cable conductor clearly visible through its insulation.
What happens if a capacitor is de-energized?
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.
How should a power supply be grounded and stored?
Be grounded and stored in the immediate area of the equipment in a manner that ensures they are used. In equipment with stored energy in excess of 5 J, a discharge point with an impedance capable of limiting the current to 500 A or less should be provided.
How do you protect a capacitor?
Protection also must be provided against the hazard of the discharge itself. Provide fully visible, manual-grounding devices to render the capacitors safe while they are being worked on. Clearly mark grounding points and use caution to prevent transferring charges to other capacitors. All grounding hooks must: Have crimped and soldered conductors.
Why are capacitors used in high voltage cables?
Capacitors may be used to store large amounts of energy. An internal failure of one capacitor in a bank frequently results in an explosion when all other capacitors in the bank discharge into the fault. Note: High voltage cables should be treated as capacitors because they have capacitance and thus can store energy.
What is a soft grounding method?
