Question

The capacitance of a capacitor with charge q and a potential difference V depends on

(1) both q and V

(2) the geometry of the capacitor

(3) q only

(4) V only

Answer 1

Correct option is : (2) the geometry of the capacitor

Capacitance of capacitor \(C=\frac{A \varepsilon_{0}}{d}\)

so capacitance of capacitor is independent of charge (q) and potential (V), it depends on geometry of the capacitor and medium between plates of the capacitor.
