Resistance of a conductor

As  depends on the material,

so R depends on the material.

According to the given formula in Eq.(i), it depends on length. Moreover resistance temperature.

If = resistance of conductor at

= resistance of conductor at ,

and  =temperature coefficient of resistance, then

The resistance of a straight conductor does not depend on shape of cross-section.
