Q2. In the circuit shown adjacent, V= 60.0 V, R, = 10.0 2, R, = 20.0 2, and [ = 3 H. (a) Immediately after the switch is closed, what is the value of the current through R.? Make sure you justify your answer. (b) Immediately after the switch is closed, what is the rate of change of current through ? Also, specify the direction (up/down) that the current flows through L. Justify your answer. (c) A long time after the switch is closed, what is the value of the current through R.? Justify your answer. (d) Once the circuit has reached a steady state (a long time after the switch was initially closed), the switch is reopened. Immediately after the switch is reopened, what is the value of the current through R.? After the switch is reopened, how much time does it take for the current in R, to reach approximately 37% of its initial value? Justify your answers
