Question

a straight wire of 40 ohm is bend and form a circular loop than calculate it's new resistance along its diameter ​

Answer 1

Answer:

given : straight wire =40ohm.

then it bend into circular loop diameter = 20 ohm;1\2=10ohm. its new resistance =2π r+ h= 222/710+20=23/72=03.28.I hope that It will we helpful to you
