Problem

A parallel-plate capacitor has plate area

200\,\text{cm}^2

and plate separation

2\,\text{mm}

. Calculate its capacitance (i) in air and (ii) when the space between the plates is completely filled with a dielectric of constant 3. (Take

\varepsilon_0 = 8.85\times10^{-12}\,\text{F\,m}^{-1}

.) (i) Capacitance in air (ii) Capacitance with dielectric
