A thermistor is a device that:
|
|
Always has a fixed resistance
|
|
|
Has a resistance that changes due to the amount of light acting upon it.
|
|
|
Has a resistance in one direction only.
|
|
|
Has a resistance that changes due to the amount of thermal energy acting upon it.

Explanation:
Detailed explanation-1: -Thermistors are thermally sensitive resistors whose prime function is to exhibit a large, predictable and precise change in electrical resistance when subjected to a corresponding change in body temperature.
Detailed explanation-2: -Temperature & Resistance An increase in temperature causes an increase in resistance. A decrease in temperature causes a decrease in resistance.
