Question

The equivalent resistance between $A$ and $B$ of the network shown in figure:

A

$11 \frac{2}{3} R$

B

$14 R$

C

$\frac{8}{3} R$

D

$21 R$

Answer

$\frac{8}{3} R$

Explanation

Solution

The wheat stone bridge is in balanced condition
$\frac{1}{Req} = \frac{1}{4R} + \frac{1}{8R}$
$Req = \frac{8R}{3}$
