Question

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. $\frac{14}{3}\mu F$

Answer 1

Answer: (D)

Given circuit is balanced Wheatstone bridge.
So capacitor of $2\mu F$ can be dropped from the circuit

$\Rightarrow C_{AB}=2+\frac{8}{3}=\frac{14}{3}\mu F$
