Question

In the given network, the value of $C$, so that an equivalent capacitance between $A$ and $B$ is $3\mu F$, is

• A. $\frac {1}{5}\, \mu \,F$
• B. $\frac {31}{5}\, \mu \,F$
• C. $48\, \mu \, F$
• D. $36\, \mu \, F$

Answer 1

Answer: (C)

$48\, \mu \, F$

Answer 2

Here, $\frac{\frac{16}{5} C}{\frac{16}{5}+C}= 3$
$C=48\, \mu F$
