(D) In a steady state,the capacitor acts as an open circuit,so no current flows through the branch containing the capacitor.The circuit consists of a $12 \, V$ battery connected in series with a $2 \, \Omega$ resistor and a $6 \, \Omega$ resistor.The total resistance of the circuit is $R_{eq} = 2 \, \Omega + 6 \, \Omega = 8 \, \Omega$.The current flowing through the circuit is $I = \frac{V}{R_{eq}} = \frac{12 \, V}{8 \, \Omega} = 1.5 \, A$.The capacitor is connected in parallel with the $6 \, \Omega$ resistor. Therefore,the potential difference across the capacitor is equal to the potential difference across the $6 \, \Omega$ resistor.The potential difference across the $6 \, \Omega$ resistor is $V_C = I 	imes R = 1.5 \, A 	imes 6 \, \Omega = 9 \, V$.The charge on the capacitor is given by $Q = C 	imes V_C = 2 \, \mu F 	imes 9 \, V = 18 \, \mu C$.

Find the charge on the capacitor $C = 2 \, \mu F$ in the given circuit in $\mu C$.
