Dear Student,

Kindly refer to page 104 of your Ncert text book part I. In an ohmic resistor the resistivity remains constant with temperature. So the graph will be a straight line parallel to the x axis.

In a metallic resistor like copper, with increase in temperature the resistivity increases.

In case of a super conductor at temperatures below a certain critical temperature the resistivity is zero, as temp increases, the resistivity increases.
