(a) Find the current through the inductor just before the switch is opened. (b) Find the current I a long time after the switch is opened. (c) Find current I as a function of time after the switch is opened. Also write the current through the cell as a function of time.

a or b c or d E = 120 V In the circuit shown In the circuit shown in fig In the circuit shown in Figure is at higher potential? (c) What is the potential difference Vcd across the inductor L? (d) Which point is at steady state. if R1 = R2= R3 =R and the current through each resistor is i. Find the currents through the resistors immediately after the switch S is opened. R1 = 30.0 Ω R2 =50.0Ω and L = 0.200 H. Switch S is closed at t=0. Just after the switch is closed.(a) What is the potential difference Vab across the inductor R1? (b) Which point
