The charge stored on a capacitor:
Q2 = 4.23 × 10-5 C
C2 = 3.6 × 10-6F
V2 = Q2/C2 = (4.23 × 10-5)/(3.6 × 10-6) = 11.75 V
Voltage across parallel capacitors is the same. C1 and C2 are in parallel.
In the figure are shown three capacitors with capacitances C1 = 6.04 × 10-6 F, C2 = 3.6 × 10-6 F, and C3 = 4.47 × 10-6 F. The capacitor network is connected to an applied potential Vab. After the charges on the capacitors have reached their final values, the charge on the second capacitor is 4.23 × 10-5 C.
(a) What is the charge Q1 on capacitor C1?
(b) What is the charge on capacitor C3?
(c) What is the applied voltage, Vab?
