four resistors and a capacitor are connected to an 18 v battery with negligible internal resistance, as shown on the diagram. Initially the capacitor is disconnected from the battery - switch is open.
(a) calculate the net resistance of the circuit.
(b) calculate the current in the 2-ohm resistor.
(c) calculate the current in the 3-ohm resistor.
switch is closed and the current reached constant value.
(d) calculate the charge on the capacitor.
(e) calculate the energy stored in the capacitor.
