The capacitance of a parallel plate capacitor is given by

C=εAdC=\frac{\varepsilon A}{d}

where CC is the capacitance,

ε\varepsilon is the permittivity of the dielectric material,

AA  is the area of the plates and

dd is the separation of the plates.

Here dd is also the thickness of the dielectric material between the plates.

(a) Since C1dC\propto \frac{1}{d} , if the thickness of the dielectric is doubled, the capacitance becomes half.

(b) Since CAC\propto A , if the effective plate is halved, the capacitance becomes half.
