Why does a capacitor offer infinite resistance at steady state
A capacitor offers infinite resistance at steady state because, in a DC (direct current) circuit, once it is fully charged, it acts as an open circuit to the steady flow of current. This occurs because a capacitor charges and stores electrical energy in the form of an electric field between its plates.
