Question

A parallel plate capacitor has a uniform electric field ‘`vec "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)

Options

• `("E"^2"Ad")/(ε_0)`

• `1/2ε_0"E"^2`

• ε₀EAd

• `1/2ε_0"E"^2"Ad"`

Answer 1

A parallel plate capacitor has a uniform electric field ‘`vec "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 `underline(1/2ε_0"E"^2"Ad")`.
