What is the resistance of a copper conductor at a temperature of 232, if at 0 it is equal to 75 ohms?

Task data: t (required temperature of the copper conductor) = 232 ºС; t0 (initial conductor temperature) = 0 ºС; R (original resistance) = 75 ohms.

Reference values: α (thermal resistance coefficient of copper) = 0.0043 K-1.

The resistance of the taken copper conductor at a temperature of 232 ºС is calculated by the formula: R = R0 * (1 + α * Δt).

Let’s calculate: R = 75 * (1 + 0.0043 * (232 – 0)) = 149.82 Ohm.

Answer: At a temperature of 232 ºС, the resistance of the taken copper conductor will be equal to 149.82 Ohm.
