Question

Q12 - A wire of resistance 20 ohm is bent in the form of a closed circle. What is
the effective resistance between the two points at the end of any diameter of
the circle​

Answer 1

Explanation:

The resistance will be same on both 2 points....

Answer 2

Answer:

wire is turned in a parallel combination of two resistance s of 10 ohm each...1/R=1/10+1/10=..so R=10/2=5....so answer is 5 ohm.
