How will the electrical energy stored on the capacitor change if the separation between the plates is doubled?Group of answer choicesIt will not change.It will quadruple.It will be cut in half.It will double.

Respuesta :

A parallel plate capacitor is connected to a battery that maintains a constant potential difference. If the separation between the plates is doubled its energy is halved.

Because the energy is inversely proportional to the separation d between the plates hence if the distance between the plates is doubled its energy is halved.

Thus, the given option It will be cut in half is correct.
