1988B3. The circuit shown above includes a switch S, which can be closed to connect the 3-microfarad capacitor in parallel with the 10 -ohm resistor or opened to disconnect the capacitor from the circuit.
Case 1: Switch S is open. The capacitor is not connected. Under these conditions determine:
a. the current in the battery
b. the current in the 10 -ohm resistor
c. the potential difference across the 10 -ohm resistor
Case II: Switch S is closed. The capacitor is connected. After some time, the currents reach constant values. Under these conditions determine:
d. the charge on the capacitor
e. the energy stored in the capacitor
