Q.
Effective capacitance between $A$ and $B$ in the figure shown is (all capacitance are in $\mu F$)
A) $21\ \mu F$
B) $23\ \mu F$
C) $\frac{3}{14}\mu F$
D) $\frac{14}{3}\mu F$
Explanation
(d) Given circuit is balanced Wheatstone bridge.
So capacitor of $2\mu F$ can be dropped from the circuit
[image:1_image346.emf]
$\Rightarrow C_{AB} = 2 + \frac{8}{3} = \frac{14}{3}\mu F$
