4. The two switches in the circuit seen in Figure below are synchronized. The switches have been closed for a long time before opening at t= 0. a. How many microseconds after the switches are open is the energy dissipated in the 4k resistor 10% of the initial energy stored in the 6H inductor? b. At the time calculated in (a), what percentage of the total energy stored in the inductor has been dissipated?
