Question

Thermistor is made up of which material?
i) Metal
ii) Semiconductor
iii) Insulator
iv) Superconductor

Answer 1

Answer:

Metals

Explanation:

As they are conductors

Answer 2

Answer:

i). Metals and

ii). Semiconductors.

Explanation:

A thermistor is a temperature-measuring device that is based on the notion that the electrical resistivity changes with temperature.

The thermistors are usually made of metal oxides with the high-temperature-coefficient of resistivity, are commonly semiconductors or metals.

For metals, the resistivity increases with increasing temperature.

For semiconductors, the resistivity decreases with increasing temperature.

Although it is less common, thermistors can be composite materials, such as a composite material with a conductive filler and a less conductive (or nonconductive) matrix.
