Explanation of Solution
Given data:
Refer to Table 12.1 in the textbook, which shows the Electrical Resistance for 1 ft long Wire, made of Various Metals Having a Diameter of 1 mil at
The relative resistance of the wire of “1 ft long and 1 mil diameter of aluminum wire” to “1 ft long and 1 mil diameter of aluminum” is calculated as,
Formula used:
Formula to calculate the relative resistance of the material is given by,
Heer,
Resistance of the copper
Calculation:
Refer to Table 12.1 in the textbook, it shows the relative resistance of 1 ft long wires with 1 mil diameter size..
Substitute 17.01 for
Therefore, the relative resistance of the aluminum is
Substitute 66.8 for
Therefore, the relative resistance of the brass is
Substitute 10.37 for
Therefore, the relative resistance of the copper metal is 1.00.
Substitute 14.7 for
Therefore, the relative resistance of the gold is 1.42.
Substitute 59.9 for
Therefore, the relative resistance of the iron is 5.78.
Substitute 132 for
Therefore, the relative resistance of the lead is 12.73.
Substitute 50.8 for
Therefore, the relative resistance of the nickel is 4.90.
Substitute 63.8 for
Therefore, the relative resistance of the platinum is 6.15.
Substitute 9.8 for
Therefore, the relative resistance of the silver is 0.95.
Substitute 70 for
Substitute 33.2 for
Therefore, the relative resistance of the tungsten is 3.20.
Substitute 35.58 for
Therefore, the relative resistance of the Zinc is 3.43.
Conclusion:
Hence the Table for relative resistance of the metals is has been created.
