Meters and troubleshootingQuestion 756 of 1506

The temperature difference across a thermocouple doubles and the other conditions are the same. What happens to the Seebeck voltage?

It stays the same
It is cut in half because the effect is not linear
It about doubles
It falls to almost zero

Show answer

Correct answer: It about doubles

The effect is fairly linear, so twice the temperature difference gives about twice the voltage.
