Question
7.4 The switch in the circuit in Fig. P7.4 has been closed for a long time. At t = 0 it is opened. a. Calculate vo(t) for t ≥ 0¹. b. Assume the switch in Fig. P7.4 has been open for one time constant. At that instant, what percentage of the total energy stored in the 0.2 H inductor has been dissipated by the 20 resistor? Figure P7.4 15 Ω t = 0 50 Ω OY EN 80 V 50 Ω 3 Ω + 30.2 Η υΣ 60 Ω Σ 20 Ω 202
