Question

The charge in the 2uf capacitor at steady state is

Answer 1

Answer :- No charge flows in 2uf capacitor at steady state.

Reason:-

In steady state there is no charge which flows in capacitor.

During steady state, supply voltage and capacitor voltage is same. As a result, no current flows since there does not exist any potential difference.

Thus, no charge flows in capacitor because of lack of potential difference.

Answer 2

Under steady state the capacitor is fully charged by the source emf. Charge stored in this condition is given by the relation,

Q = CV

Given capacitance, C = 2  μF

=> Q = 2V μc

where V is the source voltage

Under this condition the capacitor attains a voltage level same as that of the source and since the net potential difference across the source and the capacitor is zero, hence there will not be any flow of current in the circuit.
