Question

Define temperature coefficient of resistance and its si unit

Answer 1

Answer:

The "alpha "Constant is known as the temperature coefficient of resistance and symbolizes, the resistance change factor per degree of temperature change.... For pure metals, this coefficient is a positive number mean is that resistance increases.The SI unit of temperature coefficient of resistance

per degree celsius .

Answer 2

The definition is explained as follows

The SI unit of temperature coefficient of resistance is $/^{\circ}C$

Explanation:

The quantity that is used to find the change in electrical resistance of any substance per degree of temperature change is called temperature coefficient of resistance. Its relation with respect to resistance is given by :

$\dfrac{\Delta R}{R_o}=\alpha \Delta T$

Where

$R_o$ is initial resistance

$\Delta T$ is the change in temperature

$\alpha$ is the temperature coefficient of resistance

The SI unit of temperature coefficient of resistance is $/^{\circ}C$
