Question

resistance of a metal wire of length one metre is 26 ohm if the area of wire is 3 into 10 raise to the power minus 4 metre what will be its resistivity​

Answer 1

$r \: = \: \gamma \: \frac{l}{a}$

where r is resistance

l is length of conductor

a is area of cross section

and the symbol represents resistivity

Substituting all know known values into the the equation.

r = 26 ohm

l = 1m

a = 3× 10^-4
