Now let’s see how temperature affects the resistance of copper wire. A length of 18 gauge copper wire with a diameter of 1.02 mm and a cross-sectional area of 8.20×10−7 m2 has a resistance of 1.02 Ω at a temperature of 20 ∘C. Find the resistance at 0 ∘C and at 100 ∘C. The temperature coefficient of resistivity of copper is 0.0039 (C∘)−1. On a hot summer day in Death Valley, the resistance is 1.15 Ω. What is the temperature?
Calculate the resistance of a piece of 20-gauge gold wire 2.20 m long. The cross-sectional area of 20-gauge wire is 0.5176 mm2.
