Chapte 9.8 - The Thermistor Flashcards
1
Q
What is a thermistor
A
• Electrical component that resistance decreases as tempersture increases
-negative temperature coefficient (NTC)
2
Q
How does a component with a negative temperature coefficient (NTC) work
A
• Number density of charge carriers within material of component increases with temperature
3
Q
Describe ghe I-V characteristics of a thermistor
A
• Semiconductor
-non-ohmic
- As current increases temperature increases
- As temperature increases resistance decreases
