A capacitor of capacitance $^{'} C^{'}$ is being charged by connecting it across a dc 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 deflection and the resulting continuity of current in the circuit? Write the expression for the current inside the capacitor.

Answer 1

Yes. Ammeter shows a momentary deflection during the process of charging because charging electric field produce displacement current between plates of capacitor.
The resulting continuity of current in the circuit is because the magnitude of electric field and charge over an area of capacitor plates is constant.
Current inside capacitor $I_{D} = ϵ_{0} \frac{d ϕ _{E}}{d t}$

Answer 2

Yes. Ammeter shows a momentary deflection during the process of charging because charging electric field produce displacement current between plates of capacitor.

The resulting continuity of current in the circuit is because the magnitude of electric field and charge over an area of capacitor plates is constant.

Current inside capacitor

I_{D} = ϵ_{0} \frac{d ϕ _{E}}{d t}

Why does current in a steady state not flow in a capacitor connected across a battery 7 However momentary current does flow during charging or discharging of the capacitor. Explain.

A capacitor of capacitance C carrying charge Q is connected to a source of emf E. Finally the charge on capacitor would be :

A capacitor of capacitance C is charged by connecting it to a battery of e.m.f. E volts. The capacitor is now disconnected and reconnected to the same battery with polarity reversed. The heat energy developed in the connecting wire is:

The capacitive of a reactance capacitor connected to a DC source is

A capacitor made of two parallel places each of plate area A and separations d, being charged by an external ac source. How the displacement current inside the capacitor is same as the current charging the capacitor
