Negative temperature coefficient (NTC)
Negative temperature coefficient (NTC)
- If an electrical resistor has a lower resistance at higher temperatures,
it has a negative temperature coefficient (NTC).
- Usually, thermistors have a negative temperature coefficient.
Positive temperature coefficient (PTC)
- If an electrical resistor has a higher resistance at higher temperatures,
it has a positive temperature coefficient (PTC).
- Usually, metallic conductors have a positive temperature coefficient.
