Chapter 8, Problem 21.
The switch in the circuit shown in Fig. 8.53 has
been open for a long time before it closes at t = 0.
(a) Find iL(t) for t > 0.
(b) Sketch vx(t) for -4 < t < 4 ms.
Chapter 8, Problem 31.
(a) Assume that the circuit shown in Fig. 8.62 has
been in the form shown for a very long time. Find
vC(t) for all t after the switch opens.
(b) Compute vC(t) at t =3 µs.
(c) Verify your solution with PSpice.
Chapter 8, Problem 49.
With reference to the circuit shown in Fig. 8.78,
obtain an algebraic expression for and also sketch:
(a) iL(t); (b) v1(t).
Chapter 8, Problem 55.
The switch shown in Fig. 8.83 has been closed
for a very long time.

(b) Just after the switch is opened, find iL(0+).
(c) Find iL(∞).
(d) Derive an expression for iL(t) for t > 0.
Chapter 8, Problem 63.
After being open for a long time, the switch
shown in Fig. 8.89 closes at t = 0.
