1
New cards
define negative temperature coefficient
the property of a material having a lower resistance at higher temperatures
2
New cards
state why some materials have a negative temperature coefficient
temperature increases → number density of electrons increases
3
New cards
state the name of an electrical component with a negative temperature coefficient
thermistor
4
New cards
describe why a thermistor is a good detector of temperature changes
small change in temperature → larger change in resistance
5
New cards
state the I-V characteristics of a thermistor
I → V
non-ohmic conductor
resistance → decreasing
