All capacitors are initially uncharged Switch 1 is rst closed for several seconds, and then opened. Then switch 2 is closed. Calculate the nal potential differences V1, V2, and V3 across each capacitor, and indicate, on the diagram, which plate is positive and which is negative for each capacitor. Take C1 = 6.0nF, C2 = 20.0uF, C3 = 30.0pF, and the battery emf to be 9.0 volts. S1 52 C1 | C2 8 2. In figure shown, a potential difference V = 100 V ia applied across a capacitor arrangement with capacitances C1 = 10.OuF, C2 = 5.00uF, C3 = 4.00uF. What are a) charge q3, b) potential difference V3, and c) stored energy U3 for capacitor 3. d) charge q1, e) potential difference V1, f) stored energy U1 for capacitor 1 and g) charge q2, h) potential difference V2, i) stored energy U2 for capacitor 2. - - - C1 C3 C2 .
