Question

What is temperature coefficient of resistance ? In which case the value of it becomes negative ?​

Answer 1

Answer:

Coefficients approaching zero can be obtained by alloying certain metals. Anegative coefficient for a material means that its resistance decreases with an increase in temperature. Semiconductor materials (carbon, silicon, germanium) typically havenegative temperature coefficients of resistance.

Answer 2

Answer:

Coefficients approaching zero can be obtained by alloying certain metals. A negative coefficient for a material means that its resistance decreases with an increase in temperature. Semiconductor materials (carbon, silicon, germanium) typically have negative temperature coefficients of resistance...
