Question 404: Electrostatics & Capacitance

Question

A sheet of aluminium foil of negligible thickness is introduced between the plates of a capacitor. The capacitance of the capacitor

Accepted Answer

The capacitancce of parallel plate capacitor in which a metal plate of thickness $$t$$ is inserted is given by
$$C = {{{\varepsilon _0}A} \over {d - t}}.\,\,\,\,\,$$
Here $$t 	o 0\,\,\,\,\,\,$$ $$	herefore$$ $$C = {{{\varepsilon _0}A} \over d}$$
