2. With increase of temperature, the resistivity of copper -
Answers
Answer:
The Temperature Coefficient of Copper (near room temperature) is +0.393 percent per degree C. This means if the temperature increases 1°C, the resistance will increase 0.393%. Examples: You have 100 feet of 20 gauge wire and its resistance is 1.015 ohms at 20° C (room temp).
