2. a) Given the circuit shown below in figure P2, compute the inductor current, iL(t), for t≥ 0 utilizing the
generalized equation method presented in lecture. Assume the switch shown in figure P2 is ideal and
opens in zero time at t=0[s]. The current and voltage conventions shown must be used in the analysis
to receive any credit.
b) Use your answer to part 2(a) above and the relationship between the inductor current, iL(t), and the inductor
voltage, VL(t), shown below in equation P2 to compute VL(t) for t≥0.
