Solve the all parts of given question:
Question: The capacitor in an RC circuit (R = 120 ohms, C = 45 muF) is initially uncharged.
Part A: Find the charge on the capacitor in the circuit one time constant (T=RC) after the circuit is connected to a 9.0-V battery.
Part B: Find the current in the circuit one time constant (T=RC) after the circuit is connected to a 9.0-V battery.
