Question

69. The energy stored in volume V of electric field is:​

Answer 1

Answer:

uE = ½ε0E2

Explanation:

We interpret uE = ½ε0E2 as the energy density, i.e. the energy per unit volume, in the electric field. The energy stored between the plates of the capacitor equals the energy per unit volume stored in the electric field times the volume between the plates.
