At 167 degrees F, what is the resistance value for Copper?

The resistance value for copper at a specific temperature, such as 167 degrees Fahrenheit, is derived from its temperature coefficient of resistance. Copper has a known resistance of approximately 0.00393 ohms per degree Celsius, which translates to its behavior when subjected to different temperatures.

At standard room temperature (usually taken as 20 degrees Celsius or 68 degrees Fahrenheit), the resistivity of copper is about 1.68 micro-ohm centimeters. As temperature increases, the resistance of copper also increases due to the increase in atomic vibrations, which impedes the flow of electrons.

When calculating the resistance at 167 degrees Fahrenheit, the conversion to Celsius is necessary, followed by applying the temperature coefficient to determine the new resistance value. The calculated value reflects the intrinsic properties of copper and its predictable behavior when subjected to elevated temperatures.

In this context, the value of 12.9 ohms at 167 degrees F aligns with the expected changes in resistance for copper, making it the correct answer.
