Question

Resistance of metal wire of length 1 m is 26 . if diameter of wire is 0.3 mm what will resistance of metal ​

Answer 1

Answer:

Resistance of a metal wire of length 1m is 26Ω at 200C . If the diameter of the wire is 0.3mm, what will be the resistivity of the metal at that temperature?

Answer 2

Answer:

1.82×10−6Ωm.

Explanation:

Where d is the diameter of the metal wire and its value has been given as 0.3mm. Hence, the resistivity of the metal wire comes out to be 1.82×10−6Ωm.
