QUESTION

In the circuit shown in the figure (Figure 1) , E = 61.0 V , R1 = 38.0 , R2 = 28.0 , and L = 0.302 H . Switch S is closed at t=0.

In the circuit shown in the figure (Figure 1) , E = 61.0 V , R1 = 38.0 Ω , R2 = 28.0 Ω , and L = 0.302 H . Switch S is closed at t=0.

a) Just after the switch is closed, 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?

e) The switch is left closed a long time and then opened. Just after the switch is opened, what is the potential difference vab across the resistor R1?

f) Which point, a or b, is at a higher potential?

g) What is the potential difference vcd across the inductor L?

h) Which point, c or d, is at a higher potential?
