Thermistor

Description

Thermistor

Resistor is an electrical component that reduces the electric current. It opposes the flow of either direct or alternating current, employed to protect, operate, or control the circuit.

The resistor’s ability to reduce the current is called resistance and is measured in units of ohms (symbol: Ω). If we make an analogy to water flow through pipes, the resistor is a thin pipe that reduces the water flow.

A thermistor is a temperature sensitive resistor, they are often used as a temperature sensor. The term thermistor is a contraction of the words “thermal” and “resistor”. All resistors have some dependency on temperature, which is described by their temperature coefficient.
