Question

Charge on the capacitor in the given circuit in steady state condition is:
                                                             

Options

A.12 μC
B.15 μC
C.18 μC
D.6 μC

Solution


At steady state, no current through the capacitor
hence
current in circuit 1 = A

VA − VB = 9 V
q = C (VA − VB) = 2 × 9  =  18 μC
