Question

Two plates of a parallel plate capacitor separated by a layer of air has a capacitance of $15 \mu \mathrm{~F}$. If a sheet of mica with dielectric constant $k=6$ is inserted between the plates, the capacitance will be

Professor PC Thomas Classes · Answer

Capacitance with dielectric is $C' = kC = 6 	imes 15\mu	ext{F} = 90\mu	ext{F}$.
