A circuit is constructed with three resistors and one capacitor as shown. The values for the resistors are: R1 = R2 = R3 = 6.0 ?. The capacitance is C = 50 ?F and the battery voltage is V = 10 V. The switch S is initially open.
1. What is the current through R1 after the switch is closed for a long time?
2. After the switch is closed for a long time, what is the charge on the capacitor in ?C?
3. After the switch is closed for a long time it is opened. What is the current through R1 immediately after the switch is opened?
4. After the switch is closed for a long time it is opened. What is the current through R2 immediately after the switch is opened?
