In the circuit shown in Fig. 30.27, ? = 60.0 V, R1 = 40.0 n, R2 = 25.0 ?, and L = 0.300 H. Switch S is closed at r = 0. Just after the switch is closed,(a) What is the potential difference vab across the resistor R1;(b) Which point, a or b, is at a higher potential;(c) What is the potential difference Vcd across the inductor L;(d) Which point, c or d, is at a higher potential? The switch is left closed a long time and then opened. lust after the switch is opened,(e) What is the potential difference v"" across the resistor R1;(f) Which point, a or b, is at a higher potential;(g) What is the potential difference v cd across the inductor L;(h) Which point, c or d, is at a higher potential?
