12/08/2020 0183 32We want to know the resistance of a 20.0 meter long cylindrical piece of copper and the diameter of this cylindrical wire is 2.053 millimeters, which we write as 2.053 times 10 to the minus 3 meters. And the resistivity of copper, we have to look that up in table 20.1 so at 20.0 degrees Celsius, the resistivity of copper is 1.72 times 10 to the minus 8 ohm meters.: 4.5/5
