Q.
The equivalent capacitance between points $X$ and $Y$ in figure is
Electrostatic Potential and Capacitance
Solution:
Equivalent circuit may be drawn as follows:
As the structure is balanced Wheatstone bridge, so $5\, \mu F$ capacitor will draw no charge from battery and may be removed. Now the circuit is a simple circuit.
$C_{\text {eq }}=\frac{4 \times 6}{(6+4)}+\frac{3 \times 2}{(3+2)}=\frac{18}{5} \,\mu F$
