Refer to the following information for the next two questions.
Given below is a table of a sample of the lengths and diameters of different gauges of solid copper wire.
Refer to the following information for the next two questions.
Borrowing a more sensitive meter, a measurement for the resistance of each wire was later obtained. The results are shown in the table below.
Based on the graph shown below, what can be determined regarding the relationship between the resistance per unit length of each wire and the cross sectional area of each wire? |
Refer to the following information for the next five questions.
To rectify this data, the next step was to plot R/L vs 1/A.
As shown in this picture, copper wire comes both solid and stranded. Why for this lab did the teacher choose to not use samples of stranded wire? |
