What is the resistance value for Aluminum at 167 degrees F?

The resistance value for aluminum at elevated temperatures, such as 167 degrees Fahrenheit, is important for various electrical and fire alarm system applications, as it can affect the performance of conductors.

At 167 degrees F, the resistance of aluminum increases due to the temperature coefficient of resistance, which indicates how the electrical resistance changes with temperature. Typically, for aluminum, the resistance values can be derived from reference tables or calculated using formulas that account for the change in temperature.

The correct value of 21.2 ohms reflects the expected increase in resistance from the standard room temperature value. Understanding how temperature impacts the resistance of conductors is crucial for ensuring efficient power delivery and system reliability in fire alarm systems. This knowledge helps technicians design and troubleshoot systems effectively, ensuring that all components function correctly under varying environmental conditions.
