Quizplus · Accepted Answer

The total capacitance of the circuit is 125µF. Using the formula Q=CV, the charge on each capacitor is Q=CV=(125x10^-6 F)x(1000V)=0.125C. Since each capacitor has two plates, the charge on each plate is half of the total charge, which is 0.125C/2=0.0625C. Therefore, the answer is closest to 0.5C, which is choice B.
