Question

v) Temperature coefficient of resistance​

Answer 1

Answer:

The resistance-change factor per degree Celsius of temperature change is called the temperature coefficient of resistance. This factor is represented by the Greek lower-case letter “alpha” (α). A positive coefficient for a material means that its resistance increases with an increase in temperature.

Answer 2

$\huge\bigstar\underline\mathcal\blue{Answer:-}$

Temperature coefficient of resistance:

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.
