Thermistors are generally fabricated from which type of material?

1. Metal oxides that have a large temperature coefficient of resistivity
2. Metals that have a large temperature coefficient of resistivity
3. Metals that have a small temperature coefficient of resistivity
4. Semiconductors with a small temperature coefficient of resistivity

Correct answer: Metal oxides that have a large temperature coefficient of resistivity

Solution

Thermistors are made from metal oxides (semiconducting) that have a large temperature coefficient of resistivity, giving a strong, usually negative, change of resistance with temperature.
