Question 301: Current Electricity

Question

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 -

Accepted Answer

R
eq
berween any two vertex will be
$${1 \over {{{\mathop{m R}
olimits} _{eq}}}} = {1 \over {12}} + {1 \over 6} \Rightarrow {{\mathop{m R}
olimits} _{eq.}} = 4\Omega $$

Answer

12 $$\Omega $$

Answer

2 $$\Omega $$

Answer

4 $$\Omega $$

Answer

8 $$\Omega $$
