Unformatted text preview: 4) In Situation 25.1, the potential difference across the capacitor is closest to: A) 45 V B) 75 V C) 30 V D) 90 V E) 60 V 5) In Situation 25.1, the surface charge density on the plates, in m C/m 2 , is closest to : A) 11 B) 13 C) 9 D) 7 E) 15 1 Figure 25.3 The network shown is assembled with uncharged capacitors X, Y, and Z, and open switches, S 1 and S 2 . A potential difference V ab = +120 V is applied between points a and b. After the network is assembled, switch S1 is closed, but switch S 2 is kept open. 6) In Figure 25.3, the voltage across capacitor Z, in SI units, is closest to: A) 80 B) 20 C) 100 D) 40 E) 60 7) A 5.0-m F capacitor has a potential difference of 5.0 V applied across its plates. If the potential difference across its plates is increased to 9.0 V, how much additional energy does the capacitor store? A) 280 m J B) 80 m J C) 40 m J D) 140 m J 2 Answer Key Testname: 1BB-QUIZ2 1) C 2) C 3) D 4) A 5) B 6) A 7) D 3...
