The I-V chaacteristics of a resistor is observed to deviate from a straight line for higeher value of current as shown in fin 5.17 why?

The I-V characteristics of a resistor is observed to deviate from a straight line for higher value of current as shown in fin 5.17 why?

While stud dying the dependence of potential difference (V) across a resistor on the current (I) passing through it, in order to determine the resistance of the resistor, a student took 5 readings for different values of current and plotted a graph between V and I. He got a straight line graph passing through the origin. What does the straight line signify? Write the method of determining resistance of the resistor using this graph.
