The due time is Central time. 001 (part 1 of 1) 10 points A circuit consists of a 32 Ω 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? Answer in units of 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. L R E S b a I ( t ) Suppose we replace the inductor with one of the same area and length, but twice as many turns. The time required for current to drop to one-half its initial value, I ( t ) = 1 2 I 1. increases by exp(2)....
