    Does its resistance change?

    What we found: The graph is not a straight line which shows that the nichrome wire does not obey Ohm's Law, that is, it is non-ohmic.

    As the relationship is not linear, the graph is NON OHMIC.

    Ohms law states that the Voltage (Potential Difference) and Current of a circuit are both DIRECTIONALLY PROPORTIONAL to each other - therefore a graph produced displaying the relationship between the two would be linear.

    Hope this helps!
