Question
The circuit at right contains two resistors, a voltage source, an inductor, and a switch. the switch has been at position A for a very long time. At t = 0 the switch is thrown to position B
. DATA: R1 = 5.5 k hom, R2 = 9.2 k hom, L = 320 mH, deltaVs = 25 V
(a) What is the value of the time constant, JB?
(b) Let t1 = 65 E-6 s. What is the current in the circuit at time t1?
(c) What is the induced voltage across the inductor at time t1?
(d) What is the voltage across the resistor at time t1?
(e) At time t1 the switch is thrown to position A, thereby defining the time t
