The Electrical Resistivity of Graphite

Therefore, a straight-line graph should result. Now determine the slope of the line. Since R= L/A, the slope of a graph of R vs. L is /A. C. The relationship between resistance and width. 3. Draw a line about 8-mm wide and 5-cm long. Draw a second line below it about 4-mm wide and 5-cm long. ................
