a wire of resistance R is coiled in the form of circle then the equivalent resistance between points A and B is ​

Answer 1

Answer:

Explanation:

Resistance is proportional to length

That's why resistance of bigger arc is 3/4 of r and resistance of smaller arc is 1/4 of r

and both are in parallel

Req=3r/4×1r/4/(3r/4+1r/4) =3r/16
