7.6 The two switches in the circuit seen in Fig. P7.6 are

7.6 The two switches in the circuit seen in Fig. P7.6 are synchronized. The switches have been closed for a long time before opening at t = 0. 01 a) How many microseconds after the switches are open is the energy dissipated in the 4 kn resis- tor 10% of the initial energy stored in the 6 H inductor? b) At the time calculated in (a), what percentage of the total energy stored in the inductor has been dissipated? Figure P7.6 1=0, 1105 mA 1 kn 6 H. 4 20 80 kn
