Review the Concept of Temperature Coefficient of Resistance.

Answer 2

Answer:

Here is the ans hope its helpful for you☺

Explanation:

The temperature coefficient of resistance for a resistor is determined by measuring the resistances values over an appropriate temperature range. The TCR is calculated as the average slope of the resistance value over this interval. This is accurate for linear relations, since the TCR is constant at every temperature.
