Question 295 of 380

Five equal resistances are connected in a network as shown in figure. The net resistance between the points $A$ and $B$ is :

A$R$B$\dfrac{R}{2}$C$\dfrac{3R}{2}$D$2R$

Show answer and solution▾

Answer: (A) $R$

This diagram can be drawn like

It is a wheat stone bridge
$∴{R}_{eq}=\dfrac{2R\times 2R}{2R+2R}\Rightarrow R$
