Chapter 23, Problem 40P

(choose chapter or problem)

(III) A \(7.7-\mu F\) capacitor is charged by a 125-V battery (Fig. 17–29a) and then is disconnected from the battery. When this capacitor \(\left(C_{1}\right)\) is then connected (Fig. 17–29b) to a second (initially uncharged) capacitor, \(C_{2}\), the final voltage on each capacitor is 15 V. What is the value of \(C_{2}\)? [Hint: charge is conserved.]
