The charge on 4 mF capacitor in the given circuit is .... in mC [Kerala PMT 2004]

A)            12

B)                    24

C)                    36

D)                    32

Correct Answer: B

Solution :

                   Equivalent capacity between A and B \[=\frac{6\times 4}{10}=2.4\,\mu F\] Hence charge across 4mF (Since in series combination charge remains constant) or \[\text{6}\mu F=\text{ 2}.\text{4}\times \text{1}0\text{ }=\text{ 24}\mu C\]
