Unformatted text preview: gonzales (pag757) Homework 11 Hoffmann (56745) 1 This printout should have 23 questions. Multiplechoice 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 After the parts that are withdrawn there are 20 problems. 001 (part 1 of 2) 10.0 points A smalldiameter inductor with self inductance L s and a largediameter inductor with selfinductance L are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 selfinductance 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 L eq = radicalBig ( L s + L ) 2 002 (part 2 of 2) 0.0 points WITHDRAWN 003 (part 1 of 2) 10.0 points A smalldiameter solenoidal inductor with selfinductance 131 mH and a largediameter solenoidal inductor with selfinductance 54 mH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 selfinductance 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 Answer in units of mH. 004 (part 2 of 2) 0.0 points WITHDRAWN 005 (part 1 of 3) 10.0 points A capacitor of 66 F is connected in series to an inductor of 30 mH and to an open switch.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?...
