The energy of a capacitor with a capacity of 8pF and a voltage between the plates of 1000V is …?

Given:

C = 8 picofarads = 8 * 10 ^ -12 Farads is the capacity of a charged capacitor;

U = 1000 Volts – voltage between capacitor plates.

It is required to determine the energy of the charged capacitor W (Joule).

To determine the energy of a charged capacitor, you need to use the following formula:

W = C * U ^ 2/2 = 8 * 10 ^ -12 * 1000 ^ 2/2 = 4 * 10 ^ -12 * 10 ^ 6 =

= 4 * 10 ^ -6 Joules = 4 μJ.

Answer: The energy of a charged capacitor is 4 microjoules.
