Question

The uniform wire form a circular ring. The resistance across any 2 points at 60 degree is 5 ohms, then what is the resistance of wire?

Answer 1

if for 60° it is 5 ohms then the wire is circular which means 360°
then 60° ÷5 = 360° ÷x
60° × x = 360° × 5
x = 1800° ÷ 60°
x = 30 
therefore 30 ohms is the ans
