The capacitance of a parallel-plate capacitor does not depend on

1. Area of the plates
2. Medium between the plates
3. Distance between the plates
4. Metal of the plates

Correct answer: Metal of the plates

Solution

For a parallel-plate capacitor, $C=\varepsilon A/d$. Thus capacitance depends on plate area, separation, and the medium (dielectric) between the plates. It does not depend on the metal used for the plates.
