Question

what will happen if diameter is halved of a conductor​

Answer 1

Hope my answer helps you...

Answer 2

Answer:

If the diameter is halved the cross-sectional area is quartered and the resistance is quadrupled. so if the radius doubles the area will quadruple and, given constant resistivity, length, and temperature, the resistance of a conductor will vary inversely with its cross-sectional area.
