Problem

Which one of the following expressions gives the capacitance

C

(in vacuum) of a parallel-plate capacitor having plate area

A

and plate separation

d

? a)

C = \dfrac{\varepsilon_0 A}{2d}

C = \dfrac{\varepsilon_0 d}{A}

C = \dfrac{\varepsilon_0 A}{d}

C = \dfrac{\varepsilon_0 d^{2}}{A}
