(a) Switch S is closed. At some time t afterward the current in the inductor is increasing at a rate of di/dt = 50.0 A/s. At this instant, what is the current i1 through R1 and the current i2 through R2?
i1 = 1 A
i2 = 2 A
(b) After the switch has been closed a long time, it is opened again. Just after it is opened, what is the current through R1?
