Chapter 7, Problem 7.25(choose chapter or problem)
In the circuit shown in Fig. P7.25, both switches operate together; that is, they either open or close at the same time. The switches are closed a long time before opening at t = 0. a) How many microjoules of energy have been dissipated in the 12 kfl resistor 12 ms after the switches open? b) How long does it take to dissipate 75% of the initially stored energy?
