A capacitor of capacitance 'C' is being charged by connecting it across a d.c. source along with an ammeter. Will the ammeter show a momentary deflection during the process of charging ? If so, how would you explain this momentary deflectin and the resulting continuity of current in the circuit ? Write the expression for the current inside the capacitor.
