Answer:
effective resistance will be R
Explanation:
the wire is bent into a circle
hence the resistance will be divided into 2 parts which is
2r on the upper half and 2r on the lower half
now the parallel of 2r and 2r will be
2R*2R/2R+2R
= 4R^2/4R
= R

Answer:
A wire of 4 r bended.....
Now,
In parallel,
2r/2r =4r ,
where the wire divided into resistance....
2r*2r/2r+2r
= 4r2/4r
=8r /4r
= 2r is the answer......
please mark me brainliest.....
