The temperature (T) dependence of resistivity ( ) of a semiconductor is represented by

Correct answer

1

Step-by-step solution

The variation of specific resistance with temperature is given by = ₀ [1+ (T-T₀ ) ] where = temperature coefficient of resistance which is negative for semiconductor. = ₀- ₀ (T-T₀ ) Comaring with straight line equation, y=m x+c m , slope is negative.
