What is a thermister in physics?
0:02
Definition. A thermister is a
0:04
temperature sensitive resistor whose
0:06
resistance changes significantly with
0:08
temperature. The word thermostatrmister
0:11
comes from thermal heat and resistor.
0:13
Explanation thermisters are made from
0:16
semiconductor materials. Unlike ordinary
0:19
resistors, their resistance is not
0:22
constant. It varies with temperature.
0:24
NTC negative temperature coefficient
0:27
thermister resistance decreases when
0:29
temperature increases. PTC positive
0:32
temperature coefficient thermister
0:35
resistance increases when temperature
0:37
increases. This property makes
0:39
thermostatrmers useful for measuring
0:41
temperature, protecting circuits from
0:44
overheating or automatically controlling
