A parallel plate capacitor has a uniform electric fieldE→in the space between the plates. If the distance between the plates isdand the area of each plate isA, the energy stored in the capacitor is:ε0=permittivity of free space)NEET 2021

Options:

Answer:
C
Solution:

Electric energy density x=12ε0E2

Volume of the space between plates of Capacitor is Ad.

∴ Energy Stored = Energy density × Volume

=12ε0E2Ad
