Question

In the network as shown in fig, each resistance r is of $2\Omega$. Find the effective resistance between points A and B.

Answer 1

Given,

$r=2\Omega$

The equivalent resistance between A and B,

$R_{eq}=\frac{8r}{7}\Omega$ (from the above figure)

$R_{eq}=\frac{8\times 2}{7}\Omega$

$R_{eq}=2.2857\Omega$
