Question

2. Consider the circuit diagram shown. The resistors have different resistance values: R, 2R, and 3R. The circuit is not energized (as shown) until the switch SW is moved to the upper position at t 0. Answer the following questions in terms of Vo, R, and L SW (a) What is the current delivered by the battery at R 0? (b) What is the current delivered by the battery after a long time? (c) How would you define "a long time"? (d) What is the energy stored in the inductor after a long time? (e) What is the potential difference across the 3R resistor after a long time? va 2R 3R After a long time, the switch is moved to the lower position. The switch operates in such a way that the change from upper to lower position is instantaneous and the current is not interrupted during the change in position. This move defines a new t = 0. (f) Write an expression for current through the inductor starting at the newt = 0.
