What transducer converts a change in temperature into a change in resistance?
A) thermometer
B) thermocouple
C) thermistor
D) thyristor

Question

Quizplus · Accepted Answer

A thermistor is a type of temperature sensor that converts a change in temperature into a change in resistance. As the temperature increases, the resistance decreases, and vice versa. Thermocouples also measure temperature but generate a voltage instead of a change in resistance, while a thermometer is simply an instrument for measuring temperature and does not convert the change into an electrical signal. A thyristor is a type of semiconductor device used in power control circuits and does not have a temperature sensing function.
