What is the name of the semiconductor that decreases in resistance with an increase in temperature?

AI Explanation
The correct answer is B) thermistor. A thermistor is a type of semiconductor whose electrical resistance decreases as its temperature increases. This makes it the correct choice for a semiconductor that exhibits this inverse relationship between resistance and temperature. The other options are incorrect because: A) A resistor does not have a temperature-dependent resistance. C) A thermopile is a type of thermoelectric device, not a semiconductor. D) A diode is a semiconductor, but its resistance does not decrease with increasing temperature.
