Solution
- According to Maxwell's hypothesis, a displacement current will flow through a capacitor when the potential difference across its plates is varying.
- Thus a varying electric field will exist between the plates and this displacement current is the same in magnitude as the current flowing in the outer circuit.
- When a D.C voltage is applied across its plates, a constant voltage appears across its plates and so there will be no displacement current flowing through the capacitor.
Hence, the displacement current will flow when the potential is varying with time.
