Degree Celsius. This means that for every degree Celsius increase in temperature, the resistance of the wire increases by 0.00125 times its original resistance.

For example, if the original resistance of the wire is 100 ohms and the temperature increases by 10 degrees Celsius, the new resistance of the wire would be:

100 ohms x (1 + 0.00125 x 10) = 101.25 ohms

Conversely, if the temperature decreases by 10 degrees Celsius, the new resistance would be:

100 ohms x (1 - 0.00125 x 10) = 98.75 ohms
