What Is Temperature Coefficient of Resistance?

The temperature coefficient of resistance (α) quantifies how much the resistance of a material changes with temperature, typically expressed in per degree Celsius.

🔑

Key Points to Remember in Temperature Coefficient of Resistance

A positive α indicates that resistance increases with temperature, while a negative α indicates a decrease.
