The four capacitors, each of 25 μF are connected as shown in fig. The dc voltmeter reads 200 V. The charge on each plate of capacitor is

1. 2 × 10⁻³ C
2. 5 × 10⁻³ C
3. 2 × 10⁻² C
4. 5 × 10⁻² C

Correct answer: 2 × 10⁻³ C

Solution

The capacitors are connected in a combination of series and parallel. The equivalent capacitance is calculated, and the total charge is found using Q = CV. For each capacitor in series, the charge remains the same. Using the given values, the charge on each plate is 2 × 10⁻³ C.
