Resistivity of a wire graph

WebThe resistivity of a substance is a constant at a fixed temperature. But it will be different for different materials. It does not depend upon shape, size, and length of the conductor. Therefore, with an increase in the length of the conductor, the resistivity does not change. Thus, the given statement is false. Suggest Corrections.
