Application +4 | -1

25 capacitors each of capacitance

1 \mu \mathrm{F}

are connected in series to a battery of

100 \mathrm{~V}.

The total charge stored on capacitors is

View answer and explanation

Correct option: C

4.0 \times 10^{-6} \mathrm{C}

Option C (

4.0 \times 10^{-6} \mathrm{C}

) is correct because the total charge stored is calculated using the equivalent capacitance of the series combination and the applied voltage.
