Three capacitors of capacitance `3 muF, 10 muF` and `15 muF` are connected in series to a voltage source of `100 V`. The charge on `15 muF` is

Options

A. `50 muC`
B. `100 muC`
C. `200 muC`
D. `280 muC`

Answer

C

Explanation

`(1)/(C_(eq)) = (1)/(3) + (1)/(10) + (1)/(15) rArr C_(eq) = 2muF`
Charge on each capcitor
`Q = C_(eq) xx V rArr 2 xx 100 = 200 muC`
