Difference between Thermistor and Thermocouple?

Answer

The difference between a thermocouple and a thermistor is that one of them is passive while the other is active. A thermistor consists of a resistor that is changing in its amplitude of resistance according to the temperature. Meanwhile, a thermocouple relies on voltage.
