Question

In the circuit shown in figure, the ratio of charges on $5\mu F$ and $4\mu F$ capacitor is ______.

Answer 1

FOR IMAGE 01: The parallel Connection are:

$[\frac{1}{c_{eq}}=\frac{1}{3}+\frac{1}{2+5}]$

$Q=CV$

$=6.1\times 6$

$=36.6\mu F$

Charges of $4\mu F$ capacitor$\frac{2.1}{4+6.1}\times 36.6=7.6\mu C$

Charges of $2.1\mu F$ capacitor $36.6-7.6=29\mu C$

Charges of $5\mu F$ capacitor$\frac{2}{7}\times 29=8.28\mu C$

Required Ratio $=1.08$
