Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points A certain circuit consists of an inductor of 55 mH in series with a resistor of 160 Ω. At a moment when the current in the circuit is 22 A, a switch in the circuit is opened. How long will it take for the current to fall to 8 . 8 A? Answer in units of s. 002 (part 1 of 3) 10.0 points An inductor and a resistor are connected with a double pole switch to a battery as shown in the figure. The switch has been in position b for a long period of time. 65 mH 4 . 39 Ω 9 . 5 V S b a If the switch is thrown from position b to position a (connecting the battery), how much time elapses before the current reaches 194 mA? Answer in units of ms. 003 (part 2 of 3) 10.0 points What is the maximum current in the inductor a long time after the switch is in position a ?...
