From what I understand, a capacitor is used to store electric charge and when it is fully charged it can release electricity. When I looked at a capacitor, I found two pieces of information on it:

* Capacitance (4n7)
* Voltage Rating (1kV)

As I understand, the voltage rating on a capacitor is the maximum amount of voltage that a capacitor can safely be exposed to and can store. But what about when it is fully charged and released, how much voltage can it release? Does it equal the voltage rating?
