Solution

The correct option is A 30μC
When the capacitor is fully charged , the current only flow through the resistors in this circuit.

As the two capacitors are charged by two different emf so they connected in series so charge of them is equal .i.e, q (say).

Apply Kirchhoff's law,

for loop AEHDA: 18=(1+5)i1i1=3A

for loop BCGFB: 15=(2+4)i2i2=2.5A

for loop ABCDA: 18+15=q/3+2i2+q/2+1i1

or 33=(5/6)q+2(2.5)+1(3)=(5/6)q+8

or q=25×(6/5)=30μC
