In the given circuit diagram when the current reaches steady state in the circuit, the charge on the capacitor of capacitance C will be:
Step 1: At the steady-state, the current through the capacitor is zero
Since the capacitor behaves as an open circuit, then the current through is , therefore
Current through the circuit is given by ,-------------(1)
Step 2: Calculate the voltage across the capacitor and remove resistance since no current flows through it
The voltage across the capacitor is obtained by
Step 3: Use the formula to find the charge stored in the capacitor
Hence, the correct option is (C).
