In the given circuit (as shown in figure), each capacitor has a capacity of `3 mu F`. What will be the net charge on each capacitor ?

Options

A. `48 muC`
B. `24 muC`
C. `12 muC`
D. None of these

Answer

C

Explanation

Net resistance between ABCD is `R = 4 + 1 = 5 Omega`
`therefore " " "Current" I = (V)/(R ) = (10)/(5) = 2A`
Potential difference across A and B
`= I xx 4 = 2 xx 4 = 8V`
`therefore` Two capacitors of `3mu F` each are in series
`therefore` Potential difference across each capacitor `= (9)/(2) = 4V`
Charge on each capacitor `q = CV = 3 xx 4`
