Physics - Thermistors and LDRs
What type of conductor are thermistors?
Semiconductors.
What type of conductor are LDRs?
Semiconductors.
How do thermistors and LDRs work?
They have a number density that changes in response to environmental effects.
What does the resistance-temperature graph look like for a typical thermistor?
For a typical thermistor, what does a low temperature mean?
A high resistance.
What does NTC stand for?
Negative Temperature Coefficient.
What does a Negative Temperature Coefficient mean?
- A low temperature will have a high resistance.
- A high temperature will have a low resistance.
What does a Positive Temperature Coefficient mean?
- A low temperature will have a low resistance.
- A high temperature will have a high resistance.
