Unformatted text preview: gonzales (pag757) Homework 11 Hoffmann (56745) 1 This print-out should have 23 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. After the parts that are withdrawn there are 20 problems. 001 (part 1 of 2) 10.0 points A small-diameter inductor with self- inductance L s and a large-diameter inductor with self-inductance L are connected in se- ries as shown in the figure. Consider the two inductors to be far apart. Thus, the mutual inductance between the two inductors is 0. a b Determine the equivalent self-inductance for the system. 1. L eq = radicalbig ( L s- L ) 2 2 2. L eq = L s L L s + L 3. L eq = radicalBig ( L s- L ) 2 4. L eq = L s + L 5. L eq = L s L radicalBig L 2 s + L 2 6. L eq = L s L 2 ( L s + L ) 7. L eq = L s L 2 radicalBig L 2 s + L 2 8. L eq = radicalbig ( L s + L ) 2 2 9. L eq = L s + L 2 10. L eq = radicalBig ( L s + L ) 2 002 (part 2 of 2) 0.0 points WITHDRAWN 003 (part 1 of 2) 10.0 points A small-diameter solenoidal inductor with self-inductance 131 mH and a large-diameter solenoidal inductor with self-inductance 54 mH are connected in parallel as shown in the figure. Consider the two inductors to be far apart. Thus, the mutual inductance between the two inductors is 0 mH. a b Determine the equivalent self-inductance for the system. Answer in units of mH. 004 (part 2 of 2) 0.0 points WITHDRAWN 005 (part 1 of 3) 10.0 points A capacitor of 66 F is connected in series to an inductor of 30 mH and to an open switch. The capacitor is first charged to a voltage of 240 V. The charging battery is then removed, and the switch is closed. What is the maximum charge on the capac- itor?...
