Assume that the switch has been closed a long time. 1.) Find the current through the inductor before the switch is opened. 2.) Find the voltage in the right resistor before the switch is opened. 3.) Find the current in the right resistor right after the switch is closed. My question here is how do you treat both resistors? My hunch tells me that the right resistor is irrelevant, and that loop should be treated as superfluous, but I'm not sure. If anyone could answer that question, I would greatly appreciate it. Thanks.
