At What Temp Will The Resistance Of A Copper Wire?

by

At What Temp Will The Resistance Of A Copper Wire? 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

What Happened To The Flow Of Current As You Increase The Thickness Of The Wire?
