Question

(a)what will be the resistivity of a metal wire of 2m length and 0.6mm in diameter, if the resistence of a wire is 50ohm
restivity of (p) =?
(b) The resistance of an electric wire of an alloy is 10 ohm. If the thichness of the wire is 0.001m, and length is 1m, find its resistivity.
pls pls solve both the answers ​

Answer 1

Answer:

i think that your question is incorrect because answer is 28,260,000ohm.meter

Explanation:

resistivity=resistance*cross-section area/length
