A parallel plate capacitor has a uniform electric field 'E' in the space between the plates.If the distance between the plates is 'd' and the area of each plate is 'A', the energy stored in the capacitor is : (ε0 = permittivity of free space)
(1) \(\frac{1}{2}\)ε0E2
(2) ε0EAd
(3) \(\frac{1}{2}\)ε0E2Ad
(4) \(\frac{E^2Ad}{ ε_0} \)
