Q1: In figure, the resistances are 2 1 R , 4 2 R , 6 3 R , 3 4 R , 5 5 R , and the ideal batteries have potential differences V V 20 1 , V V 13 2 and V V 52 3 . What are the magnitudes and directions of currents on each resistor? Q2 : Consider a series RC circuit for which M R 0 . 1 , F C 0 . 5 , and V 0 . 30 . Find a) the time constant of the circuit and b) the maximum charge on the capacitor after the switch is closed. c) If the switch is closed at s t 0 , find the current in the resistor 10 s later.
