The effective resistance between points $P$ and $Q$ of the electrical circuit shown in the figure is

Options:

Answer:

Solution:

According balanced wheat stone bridge

$\frac{1}{R_{e q}} = \frac{1}{2 R} + \frac{1}{2 R} + \frac{1}{R}$

$= \frac{1 + 1 + 2}{2 R} = \frac{2}{R}$

$R_{e q} = \frac{R}{2}$
