# The equivalent resistance between the points A and B is

$\begin{array}{1 1} (A)\;\large\frac{R}{2} & \quad (B)\;\large\frac{R}{4} \\ (C)\;R & \quad (D)\;\large\frac{R}{8} \end{array}$

Can you answer this question?

Here, the complicated looking circuit can be simplified by
labelling appropriate potential points as follows.
The circuit can be simplified as shown
The simplification shows that the effective resistance is $\large\frac{R}{2}$
