The switch in the figure below is open for t < 0 and is then thrown closed at time t = 0. Two adjacent rectangular loops, one to the left of the other, form a circuit. The left side of the left loop contains a battery of emf ℰ, for which the positive terminal is above the negative terminal. The top side of the left loop contains a resistor R, and the top side of the right loop contains a resistor 2R. The right side of the right loop contains an inductor L. The bottom side of the left loop contains an open switch S. The right side of the left loop, which is the left side of the right loop, contains another resistor R. (a) Find the current in the inductor. (Use the following as necessary: L, R, t, and ℰ for emf.) IL = (b) Find the current in the switch as functions of time thereafter. (Use the following as necessary: L, R, t, and ℰ for emf.) Iswitch =
