# Circuit with three capacitors

The above diagram is a circuit that consists of three capacitors A, B and C with capacitances $$C_0,$$ $$C_0$$ and $$2C_0,$$ respectively, and a resistor with resistance R. The voltage of the power supply, $$V,$$ is constant. Which of the following statements is correct?

a) When the switch S is open, the charged electricity of the capacitor A is twice as large as that of the capacitor B.
b) When the switch S is closed, the charged electricity of the capacitor C is twice as large as that of the capacitor B.
c) The electric energy charged on the capacitor A when the switch S is open is the same as that when the switch S is closed.
