With the switch open, C2 is charged and C1 uncharged. Whentheswitch is closed, the potential difference across C1eventuallyreaches 12v. What was the original potentialdifferenceacross C2?
For the system of four capacitors shown in the figure below, find the following. (Use C1 = 4.00 µF, C2 = 7.00 µF, C3 = 3.00, and C4 = 4.00 µF for the figure.)
(a) the equivalent capacitance of the system.
(b) the charge on each capacitor.
(c) the potential difference across each capacitor.
4. Determine the capacitance of a single capacitor that will havethe same effect as a combination shown in Fig. 1. The capacitancesof the capacitors are as follows: C1 = 100 ÂµF; C2 = 200 ÂµF; C3 =120 ÂµF; C4 = 180 ÂµF . Find the charges stored in each capacitor andthe potential differences between the plates of each capacitor ifthe voltage V between the points a and b is 100 V.(a) C1 C2 C3 (b)*----| |-----| |---*------| |------*\ /\----| |----/C4How much electric energy can be stored in such a combination of thecapacitors?ANS :
