Question 1 of 5

A thermocouple is a temperature sensor that consists of two wires made from different conductors. The junction of these two wires produces a voltage based on the temperature difference between them.

In an electronic circuit, a thermocouple can be used to:

keep the circuit at a designated safe temperature

open or close a circuit at a designated temperature

increase or decrease the temperature of a component in the circuit

link the temperature of one component in the circuit to that of another component in the circuit
