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

 

 

Answers (1)

At steady state, the voltage of the capacitor and source are equal and the potential difference between source and capacitor is zero, so no current flows. 

Momentary current does flow during charging or discharging of the capacitor since there is a potential difference between source and capacitor.
