Question

Resistance of metal wire of length 4 m is 50 Ω at 20˚C, if the diameter of wire is 0.5mm. What

will be the resistivity of wire?​

Answer 1

Answer:

Given the resistance of the wire R=26Ω, the diameter d=0.3mm=3x10-4 m, and the length of the wire l=1m. The resistivity of the given metallic wire is Read more on Sarthaks.com - https://www.sarthaks.com/24372/resistance-of-a-metal-wire-of-length-1m-is-26-at-20oc-if-the-diameter-of-the-wire-is-0-3-mm
