Version PREVIEW – Hw06 – Ross – (10219) 1 This print-out should have 19 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. Mutual Inductance 02 001 10.0 points A long solenoid carries a current 30 A. Another coil (of larger diameter than the solenoid) is coaxial with the center of the solenoid, as in the figure below. The permeability of free space is 4 π × 10 7 N / A 2 . 7 m 2 m Outside solenoid has 190 turns Inside solenoid has 7600 turns 13 . 9 cm 3 . 9 cm Find the mutual inductance of the system. Correct answer: 0 . 00123868 H. Capacitive Reactance 002 10.0 points A certain capacitor in a circuit has a capaci- tive reactance of 13 . 2 Ω when the frequency is 168 Hz. What capacitive reactance does the capac- itor have at a frequency of 7060 Hz? Correct answer: 0 . 314108 Ω. Serway CP 21 19 003 (part 1 of 4) 10.0 points A 15 μ F capacitor and a 28 H inductor are connected in series with a 60 Hz source whose rms output is 109 V.

### What students are saying

• 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.
