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  - Used Q = C V. Correct units and answer. B  - Used Q = C V. However, disregarded the micro in the farads and hence the charge. C  - Used Q = C V but used 5 V instead of 3 V. D  - Used Q = C V but had Amps instead of Coulombs. E  - Used Q = C V but had no units. Z  – Multiple errors in the Q = CV calculation F  – Worse than Z G  - Had some physics down but nothing relevant to the problem. H  - 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...
