Question: Q. 2. 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 capacitor. Explain.
A [O.D. III 2017]
Show Answer
Solution:
Ans. (i) In steady state no current flows because we have two sources (battery and fully charged capacitor) of equal potential connected in opposition.
(ii) During charging/discharging, there is a momentary flow of current as the potential of the two sources are not equal to each other.
