Q. The thermistors are usually made of
A) Metals with low temperature coefficient of resistivity
B) Metals with high temperature coefficient of resistivity
C) Metal oxides with high temperature coefficient of resistivity
D) Semiconducting materials having low temperature coefficient of resistivity
Explanation
(c) They are the resistors made up of semiconductors whose resistance decreases with the increase in temperature. This implies that they have negative and high temperature coefficient of resistivity.
They are usually made of metal oxides with high temperature coefficient of resistivity.
