Question

Capacitors Cl - 15 mu F 9nd C2 - 21 mu F are each charged to 25V. then disconnected from the battery without changing the charge on the capacitor plates. The two capacitors are then connected in parallel, with the positive plate of C1 connected to the negative plate of C2 and vice versa Afterward, what is the charge on each capacitor? Express your answer using two significant figures. Enter your answers numerically separated by a comma.

Explanation / Answer

Q1=Q2 = (C2-C1)*V = (21-15)*25 = 150 uC

V1 = Q1/C1 = 10 V


V2 = Q2/C2 = 7.1429 V
