Question

What ie the equivalent capacitance of the system of capacitors between A & B as shown in the figure.

• A. $\frac{7}{6}$C
• B. $1.6$ C
• C. C
• D. None

Answer 1

The correct option is D None

In the given figure$:$

$C$ is in series with $C$ sol its equivalent is $C/2.$

Now, $C/2$ is in parallel with $C$ so its equivalent is $3C/2.$

Now ,$3C/2$ is in series with $C$ so its equivalent is $3C/2.$

Now, $3c/2$ is in parallel with $C$ so its equivalent is $8C/2.$

So$,$ equivalent capacitance between $A$ and $B$ is $8/5.$

Hence,

option $\left(D\right)$ is correct answer.
