What’s a thermistor?
Is a type of resistor whose resistance is reliant on temperature. They’re made from metallic oxide which is moulded into a bead, disk or cylindrical shape and then enclosed with epoxy or glass.
Thermistor have come into popular usage in electric circuit of heating and cooling systems, the name was derived from the phase thermally sensitive resistor. For resistor temperature rises, resistance increase and in contrast most thermistor as temperature rise, resistance decrease.
