Chapter 8, Problem 59P
The switch in Fig. 8.105 has been in position 1 for t < 0. At t = 0, it is moved from position 1 to the top of the capacitor at t = 0. Please note that the switch is a make before break switch, it stays in contact with position 1 until it makes contact with the top of the capacitor and then breaks the contact at position 1. Given that the initial voltage across the capacitor is equal to zero, determine v(t).

For the two-source circuit of Fig. 8.89, note that one source is always on. (a) Obtain an expression for i(t) valid for all t; (b) determine at what time the energy stored in the inductor reaches 99 percent of its maximum value.
The switch in Fig. 8.73 is moved from A to B at t = 0 after being at A for a
long time. This places the two capacitors in series, thus allowing equal and
opposite de voltages to be trapped on the capacitors
(d) Find vr(t), t > 0. (e) Find i(t). (f) Find vi(t) and
v2(t) from i(t) and the initial values. (g) Show that the stored energy at i = 0
plus the total energy dissipated in the 20 kS2 resistor is equal to the energy
stored in the capacitors at t = 0
For the circuit shown in Fig 8, find i, vc, and iL, as well as the energy accumulated in the capacitor and inductor.
