Question

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: ε 0 = permittivity of free space), 1 2 ε 0 E 2, ε 0 E A d, 1 2 ε 0 E 2 A d, E 2 A d ε 0

MARKS App · Accepted Answer

Electric energy density x = 1 2 ε 0 E 2 Volume of the space between plates of Capacitor is Ad . ∴ Energy Stored = Energy density × Volume = 1 2 ε 0 E 2 A d
