In the circuit illustrated above, switch S is initially open and the battery has been connected for a long time.

	(a) What is the steady-state current through the ammeter?

	(b) Calculate the charge on the 10 mF capacitor.

	(c) Calculate the energy stored in the 5.0 mF capacitor.

The switch is now closed, and the circuit comes to a new steady state.

	(d) Calculate the steady-state current through the battery.

	(e) Calculate the final charge on the 5.0 mF capacitor.

	(f) Calculate the energy dissipated as heat in the 40-ohm resistor in one minute once the circuit has reached steady state.
