## Homework Statement

## Homework Equations

## The Attempt at a Solution

First I calculated equivalent capacitance between R and M . The two 2μF capacitors are in series . Their combination is in parallel with the 1μF capacitor . Their equivalent capacitance is 2μF .

Now I found equivalent capacitance between R and T .The previously calculated 2μF between R and M is in series with 8μF capacitor .The equivalent capacitance between R and T is 8/5 μF.

Now I found equivalent capacitance between P and Q . Using nodal analysis I found it to be 44/3 μF .

The net capacitance between P and Q i.e 44/3 μF and net capacitance between R and T i.e 8/5 μF are in parallel . So, net capacitance between P and T is 244/15 μF .

Across A and B this 244/15 μF is in series with the unknown capacitor C . Their net capacitance has to be 3μF . Calculations give me value of C =732/199 μF . This is incorrect .

What is the mistake ?
