Question

Where is electrical energy stored in a parallel plate capacitor, and how can it be used?

Options

• In the field between the plates, and it can later be released back into a circuit when needed

• In the plate separation, and it is permanently retained there

• Only on the outside surfaces of the plates, and it cannot be released

• In the voltage source, and it can only be released into the dielectric

Answer 1

Charge separation stores electrical energy in the field between the plates. That energy can later be released back into a circuit when needed.
