# Q. A uniform metallic wire has a resistance of $18 \; \Omega$ and is bent into an equilateral triangle. Then, the resistance between any two vertices of the triangle is :

JEE Main JEE Main 2019

Solution:

## $R_{eq}$ between any two vertex will be $\frac{1}{R_{eq}} = \frac{1}{12} + \frac{1}{6} \; \Rightarrow \; R_{eq} = 4 \Omega$
