Which of the following devices changes resistance inverselyW ith the temperature?
A)thermocouple
B)thermistor
C)RTD
D)triac

Question

Quizplus · Accepted Answer

A thermistor changes its resistance inversely with temperature. The resistance of thermistors decreases as temperature increases and increases as temperature decreases. Thermocouples are made up of two different metals and generate a voltage proportional to the temperature difference between the hot and cold junctions. RTDs (Resistance Temperature Detectors) change their resistance directly with temperature. Triacs are electronic components used for power control and are not temperature sensitive.
