1, the reason that the charges of two capacitors are equal is the conservation of charges. If the right disk of C 1 and the left disk of C2 are regarded as a whole, and the algebraic sum of charges is 0, then Q 1=Q2. As for the total power, don't think of it as the sum of success rates, but equivalent this series capacitor to a power supply to charge it.

2. If the distance between the electrodes of the capacitor is prolonged in the active state, the capacitance of the capacitor will decrease, the voltage will increase and the power will decrease; The capacity of the other capacitor is unchanged, the voltage is reduced, and the power is reduced; The sum of the two capacitor voltages remains unchanged. If the power supply is disconnected, the distance between the two poles of a capacitor becomes wider, the capacity of the capacitor remains unchanged, the voltage increases and the capacitance decreases; The other capacitor will not change anything; The sum of the voltages of the two capacitors increases.
