In the system shown in Figure 7.55, steady-state conditions are established with the switch S closed.At t = 0, he switch is opened.
(a) Sketch the voltage and current along the system for t = 0-.
(b) Find the total energy stored in the lines for t = 0-
(c) Find and sketch the voltages across the two resistors for
(d) From your sketches of part (c), find the total energy dissipated in the resistors for t > 0.
