Prob.4a (15 points). Consider the three capacitors connected as shown. A potential difference of Vab = 120V is maintained between points a and b. All capacitors have the same capacitance 10 nF. C = 10 F C 2 Cea= (105 F 'd [i] (8 points) How much electric energy is stored in the C4 capacitor? [ii] (7 points) What is the charge on the Ci capacitor? QI = C, - VCA Q, = 10- 5 F - S Prob. 4b (10 points) A 100.0 2 bulb is connected across the terminals of a 48.0 V battery having 14.0 2 of internal resistance. What percentage of the power of the batte is dissipated across the internal resistance and hence is not available to the bulb? I 8 = 48.V R= 100 52 I m R
