Question

A uniform metallic wire has a resistance of, 18ohm and is bent into an equilateral triangle. Then, the resistance between any two vertices of the triangle is (a) 12ohm (b) 8ohm (c) 2ohm (d) 4ohm ​

Answer 1

Answer:

The resistance in each part (side)= 6Ω

Between any two vertices (6Ω series 6Ω) parallel (6Ω)

equivalent resistance = (12) parallel 6Ω

= (12x6)/(18)

= 4Ω
