Question

A parallel plate capacitor has a uniform electric field `overset(->)("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

• `1/2ε_0"E"^2"Ad"`

• `("E"^2"Ad")/ε_0`

• `1/2ε_0"E"^2`

• `ε_0"EAd"`

Answer 1

A parallel plate capacitor has a uniform electric field `overset(->)("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")`.
