To determine resistance per cm of a given wire by plotting a graph for potential difference versus current

How to determine resistance per cm of a given wire by plotting a graph for potential difference versus current.
Write from below for your practical record.



CONCLUSION
Resistance per cm of the wire is found to be 0.424 Ohm/cm.
The graph between potential(V) versus current(I) is a straight line and from the graph is found to be ______ Ohm.
