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.....
