P6 - Thermistors Flashcards
what happens to the resistance in hot conditions?
It depends - If it is a negative temperature coefficient thermistor, the resistance will decrease in heat. If it’s a positive temperature coefficient, it will increase.
What is another name for a thermistor?
Temperature-Dependent Resistor
What does a negative temperature coefficient do?
It decreases resistance when temperature increases.
What is a positive temperature coefficient?
When temperature increases, resistance increases
Decreases resistance when temperature increase. What is being described?
A negative temperature coefficient (NTC)
Increases resistance when temperature increases. What is being described?
A positive temperature coefficient (PTC)
How can you make a temperature sensor?
Combine a potential divider and a thermistor.
what happens to the resistance in cool conditions?
it depends whether it’s ngative or positive temperature coefficient.
what can be uses for thermistors?
temperature sensors, car engine temperature gauge and electronic thermostats
What is the symbol for a thermister?
