5 resistors each of the same value R are connected between points A and B as shown below.Select the correct value of equivalent resistance between points A and B.

$\frac{3}{8}R$

$\text{Two resistors of value R are in parallel is } R_1 = \frac{R}{2}$

$ \text{resistors of value R and }\frac{R}{2}\text{ are in series} , \frac{R}{2} \text{is in parallel with the combination}$

$\Rightarrow \frac{3R}{2} \text{ and } \frac{R}{2}\text{ are in parallel}$

$\Rightarrow R_{eq} = \frac{3R/2 \times R/2}{2R} = \frac{3R}{8}$
