10 a) The following data was collected by measuring the potential difference across
a light bulb and the current through the same bulb. Given the values in the
table draw a potential difference versus current graph:

b) Calculate the slope of the graph: m = V/I
= 4.5/3
= 1.5 Ω
c) The slope of the graph represents the Resistance.
