Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0points 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(part1of3)10.0points 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(part2of3)10.0points What is the maximum current in the inductor a long time after the switch is in position a ?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
