Question

In the network shown in the figure, all resistors are identical with R = 300 $\Omega$. The resistance $R_{ab}$ (in $\Omega$) of the network is

$R=300\Omega$

• A. 100

Answer 1

The correct option is A 100

Modifying the given circuit

$R_{ab}={(\frac{1}{2R}+\frac{1}{R}+\frac{1}{R}+\frac{1}{2R})}^{-1}$

$=\frac{R}{3}=\frac{300}{3}=100\Omega$
