Unformatted text preview: Name: Solution , Rubric DL Section: 00 Last First Office Use Quiz 5 Physics 7B Winter 2010 Feb. 10, 2010 Consider the circuit shown above. The switch is initially open. a) When the switch is closed, the capacitor starts to charge. It will eventually (after and long time) reach a voltage of 3.0 V. How much charge is stored on the capacitor when it has charged up to 3.0 V? C = Q/V Q = CV = ( 100 F)(3V) = 3 x 10-4 C A [10] - Used Q = C V. Correct units and answer. B [9] - Used Q = C V. However, disregarded the micro in the farads and hence the charge. C [7] - Used Q = C V but used 5 V instead of 3 V. D [6] - Used Q = C V but had Amps instead of Coulombs. E [5] - Used Q = C V but had no units. Z [4] – Multiple errors in the Q = CV calculation F [2] – Worse than Z G [1] - Had some physics down but nothing relevant to the problem. H [0] - Had something completely irrelevant written down or left blank b) After the capacitor is fully charged, then switch is then opened again and the capacitor will...
