Question

The equivalent resistance between $A$ and $B$ is :

• A. $\frac{7}{5}\Omega$
• B. $\frac{13}{5}\Omega$
• C. $\frac{16}{5}\Omega$
• D. $2\Omega$

Answer 1

The correct option is C $\frac{16}{5}\Omega$

The given circuit can be redrawn as :


The above figure can be further simplified as :

Here, the net resistance between $A$ and $B$ is given by :
$R_{AB}=2+\frac{2\times 3}{2+3}=\frac{16}{5}\Omega$
