Procedure (Simulation 2): Investigating the relationship between the resistance (R) of a wire and its Cross-sectional Area. 1. For the same wire type that you select for the previous procedure, select a particular length and keep this length constant for this part of the simulation. Length of the wire = _7 m 2. Now vary the diameter of the wire and for each diameter you select, record the diameter and the resistance of the wire in the following table. Diameter, d (m) Cross-sectional Area, Resistance, R ( 12 A (m 0.4mm 1.23 m 2 0.8mm 0.24 m 1.2mm 0.12 m 4 1.4mm 82.66 m 5 1.8mm 44.99 m 6 2mm 38.38 m 3. Plot a graph Resistance (R) (on y axis) versus reciprocal of the cross-sectional area (1/A) (on X-axis). 4. Calculate the resistivity of the wire type that you choose using the slope of your graph.
