In this part of the experiment, you will investigate the physical parameters that have an effect
on the resistance of a conductor. The conductors to be used are given as in the following,
Brass (0.00203 cm")
Brass (0.00519 cm")
Brass (0.00811 cm?)
Brass (0.0127 cm)
Copper (0.00811 cm')
Aluminum (0.00811 cm)
Stainless Steel (0.00811 cm³)
Nichrome (0.00811 cm')
Part B: Resistance vs Cross-Sectional Area (A):
Task: In this part, resistance of four brass wires with different diameters thus cross-sectional
areas are to be measured. (I = 1A)

Question: How did the resistance of the conductor change with respect to cross-sectional
area? Did the change occur as you have expected?
Your Answer:
Task (Plot): Resistance vs Cross sectional area (A) graph. (Independent variable A on x-axis,
| dependent variable R on y-axis)
