Question

Temperature coefficient of resistance of semiconductor is

• A. zero
• B. constant
• C. positive
• D. negative

Answer 1

The correct option is D negative

The temperature coefficient of resistance of a semiconductor is negative. It means that resistance decrease with increase of temperature. This results in a higher number of charge carriers available for recombination, increasing the conductivity of the semiconductor. The increasing conductivity causes the resistivity of the semiconductor material to decrease with the rise in temperature, resulting in a negative temperature coefficient of resistance.
