1. The problem statement, all variables and given/known data its ohmic or non ohmic?if ohmic why?if non ohmic why?
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!
