When a parallel plate capacitor is being charged by a dc battery why does a galvanometer show a momentary defection ? Obtain the expression for the displacement current and show how it is related to conduction current in a steady state.

When capacitor is connected to the battery then charge accumulated on the plates of capacitor ,this process continue till the potential difference of capacitor become equal to the battery, hence due to this flow of charge galvanometer show momentary deflection . Now id=dQ/dt, flux=E.A = Q/A now d flux/dt = dQ/ €×dt . Hence id = € dflux /dt
