Question

In steady state, charge on capacitor is :

• A. $12\mu C$
• B. $16\mu C$
• C. $36\mu C$
• D. $28\mu C$

Answer 1

The correct option is D $28\mu C$

At steady state capacitor will be open circuit

Let voltage across capacitor is $V$

Applying KCL at node

$\frac{18-V}{2}=\frac{V-12}{1}18-V=2V-2442=3VV=14V$

We know that

$q=cv=2\mu \times 14=28\mu F$
