Question

The thermistors are usually made of

(a) metals with low temperature coefficient resistivity

(b) metals with high temperature coefficient of resistivity

(c) metal oxides with high temperature coefficient of resistivity

(d) semiconducting materials having Iow temperature coefficient of resistivity

Answer 1

Correct Option(c) metal oxides with high-temperature coefficient of resistivity

Explanation:

Thermistors are the resistors made up of semiconductors whose resistance decreases with the increase in temperature. This implies that they . have a negative and high-temperature coefficient of resistivity.

They are usually made of metal oxides with a high the temperature coefficient of resistivity.
