Multiple-choice questions may continue on the next column or page find all choices before answering. The due time is Central time. 001 (part 1 of 1) 10 points A circuit consists of a 32 resistor and a 740 mH inductor connected in series to a 17 V battery. What is the value of the current when the current is increasing at the rate of 4 A / s? Correct answer: 0 . 43875 A. Explanation: Let : R = 32 , L = 740 mH = 0 . 74 H , V = 17 V , and i i = 4 A / s . In an RL circuit V = L i t + i R i = V- L i t R i = 17 V- (740 mH)(4 A / s) 32 i = 0 . 43875 A 002 (part 1 of 1) 10 points In the circuit below a steady current I is flowing when the switch is in position a. If the switch is then thrown to position b, the current will decrease to zero after some time....
