Question

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.

Answer 1

• This is due to the enough repulsion force due to the charges which get accumulated on the plates , which generate enough repulsive force to stop the electric current
• .During charging , charge starts accumulating on the plates slowly causing not enough repulsive force to stop the current. but when it get fully charge enough force is available to do so. similar is the case of discharging.Moreover during charging or discharging electric field continuously changes between the plates causing a displacement current between the plates.
• The momentarily current .since only changing electric field produces displacement current therefore momentarily current flow only during charging or discharging. And will become zero either when capacitor is fully charges or discharged.
