A. thermometer.
B. thermostat.
C. thermistor
D. thermopile.

Correct Answer:

Option C – thermistor

Explanation

A thermistor is a resistance thermometer or a resistor whose resistance is dependent on temperature. The term is a combination of “thermal” and “resistor”. It is made of metallic oxides, pressed into a bead, disk, or cylindrical shape, and then encapsulated with an impermeable material such as epoxy or glass.

Thermistors act as a passive component in a circuit. They are an accurate, cheap, and robust way to measure temperature.
