First, we define that the diameter of our wire is taken in thousandths of an inch where one one-thousandth of an inch is called “one mil.” Thus, 0.001 inch = 1 mil, 0.01 inch = 10 mils and so forth.

Plot a graph of resistance, R, in Ω on the y-axis against cross section area, A, in mm 2 on the x-axis. Draw the line of best fit. We can see from the graph that as the cross section area, A ...

Illustrated below is the cross sectional area of 12 AWG wire showing the radius of the wire (r) and skin depth (S). Note: Multi stranded 12 AWG wire cross sectional area is slightly larger than ...

The control variables are kept the same by: not changing the wire during the experiment (material, length and cross section area of the wire stay the same); keeping the current small (temperature ...

A multi-strand wire also offers more mechanical strength then a single-strand wire. Prakhar Verma. Raigarh. This week’s questions. How do astronauts protect themselves from radiation in outer space?
