Question

A wire of resistance 8 ohm is bent in the form of a circle.The effective resistance between ends of any diameter is...

WILL MARK BRAINLIEST...FOR CORRECT..ANSWER

Answer 1

Final Answer : 2ohm

Steps and Understanding :
1) Since, Diameter divides the circle in two equal parts .
So, each part is of 4ohm.

2) Both are Parallel along a diameter.
So, Effective Resistance is
$\frac{1}{r} = \frac{1}{4} + \frac{1}{4} \\ = > \frac{1}{r} = \frac{1}{2} \\ = > r = 2ohm$
So, Effective Resistance between ends of a diameter is 2ohm.
