Question

(b) A wire of resistance 5 W 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

First of all you have written the unit of resistance as W which is wrong. Unit of resistance is ohm.


Hope it helps you.

Answer 2

Explanation:

first of all resistace is measured in ohm

total resistance =5

when drawn in circle and effective resistance between two points of diameter means half length and resistace is directly proportional to length then

r=5/2

r=2.5 ohm
