Capacitors — Collection of Solved Problems
Charges on capacitors in series are equal to each other and in this case also equal to the total charge. Therefore the charge on the third capacitor is equal to the total charge. If we know the charge, we can evaluate the voltage on the third capacitor. Voltages on both capacitors connected in parallel are the same.
