Energy Storage | Applications | Capacitor Guide
Capacitors used for energy storage. Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates. When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.

It''s a capacitor, which is like a buffer. It job is to smooth out the DC power by resisting changes in voltage. The capacitor is trying to keep the voltage at 20V even though you turned it off. If there were an actual load on this power supply, the load would instantly consume this buffer of energy.
How to Safely Discharge a Capacitor?
When a capacitor is disconnected from its supply voltage or power supply, the voltage (and current) it carries is maintained across its terminals, which can be dangerous. This excess electrical energy needs to be safely dissipated. This is why it''s very important to discharge a capacitor before you disconnect it to remove all its stored energy.

$begingroup$ Since the circuit is at a constant potential difference and the pulling apart of the capacitor plates reduces the capacitance,the energy stored in the capacitor also decreases. The energy lost by the capacitor is given to the battery (in effect, it goes to re-charging the battery). Likewise, the work done in pulling the plates …
PY106 Class8
PY106 Class8 3 13 A question from an old test 3. Charge In step 1, the capacitor is still connected to the battery, so V = V0 e Q = CV and C = 2C0, we have Q = 2C0V0. This is twice the value of the initial charge, Q0 = C0V0. In step 2, V is still V0, but C is increased to 6C0, so Q = 6C0V0 = 6Q0. 4.
