If the equivalent resistance between the terminal points $P$ and $Q$ is $4 Ω$ in the given circuit, then find out the resistance of $R$ in ohms

Answer:

Solution:

Equivalent circuit is,

Therefore equivalent resistance is,

$R_{e q} = \frac{R (\frac{4 R}{3})}{R + \frac{4 R}{3}}$

$4 = \frac{4 R}{7}$

$R = 7 Ω$
