Consider the circuit shown in the figure below, where L = 4.75 mH and R, = 425 Q. The switch S can be positioned at either a or b. L. ll + 24.0 V R (a) When the switch is at position a, the time constant is 15.1 us. What is R, (in kn)? kn (b) What is the current in the inductor at the instant the switch is thrown to position b?
