Question

Select the BEST answer for each questió letter in the table at the right. I. For a parallel plate capacitor: C = : If & and A are constant, what would a graph of C vs. d look like? 2. What equation is used to determine the equivalent capacitance of three capacitors in series? b. ?., C, C, C, C C+C, +C c. C +C+C C C3 C It's a trick question. Capacitors cannot be connected in series. Kirchhoff's Loop Law is based on the idea that... a. e. 3. Resistance in any one loop of a circuit is conserved. b. Current in any one loop of a circuit is conserved. Potential in any one loop of a circuit is conserved. d. c. Electric fields are unstable in circuits with more than one loop. Physics students feel very insecure with circuits with more than one loop. e. 4. If capacitors charge exactly the way the equations for charging capacitors predict, a capacitor with capacitance, C, connnected in series with a resistor with resistance, R, and a battery with voltage (EMF), &, will be fully charged... a. immediately after being connected to the battery. b. after a time duration oft-CV c. after a time duration of t CR d, after a time duration of R e. when pigs fly (i.e. never). A voltage of 120 V is attached across the metal bodies of two parked cars, which will now act like a capacitor. How much energy is stored in this capacitor? R 6 5. a. About 10' joules. b. About 10 joules. c. About 103 joules d. About 10S joules. e. About 10 joules. 02010-18 Shel T. Randkal rev 2018 0405

Answer 1

As c alpha 1/d so right answer (c) (2) In series 1/C_eq = 1/C_1 + 1/C_2 + 1/C_3 (option: a) (3) (c) potential in any loop of circuit is conserved. (kirchoff loop law) (4)(a) Immediately after being connected to battery (5) Data insufficient
