Three capacitors of `2.0, 3.0` and `6.0 muF` are connected in series to a `10 V` source. The charge on the `3.0 muF` capacitor is

Options

A. `5 muC`
B. `10 muC`
C. `12 muC`
D. `15 muC`

Answer

B

Explanation

Net capacitance `= (1)/(((1)/(2)+(1)/(3)+(1)/(6))) = 1muF`
Total energy `= CV = 1muF xx 10V = 10 muF`
Total charge on every capacitor in series system is same. So charge on `3 muF` is `10 muC`.
