Definition
Meaning and Definition
The electric potential difference (voltage) generated directly by a temperature difference across a junction of dissimilar materials.
In thermoelectric devices, the electromotive force (EMF) that arises from the thermoelectric effect, where heat energy is converted into electrical energy (Seebeck effect). It is the driving force for current in a thermoelectric circuit and a key parameter in measuring thermoelectric efficiency.

FAQ
Frequently Asked Questions
It is a specific type of voltage (electric potential difference) generated solely by the thermoelectric (Seebeck) effect.
Only in advanced textbooks, research papers, or technical manuals on thermoelectric energy harvesting, solid-state physics, or materials engineering.
Yes, in technical writing, 'thermo-emf' or 'thermoelectric voltage' are commonly used synonyms.
The Peltier effect, where an electric current causes a temperature difference across a junction, is often considered the complementary or reverse process.
The electric potential difference (voltage) generated directly by a temperature difference across a junction of dissimilar materials.
Thermoelectromotive force is usually technical/scientific in register.
Thermoelectromotive force: in British English it is pronounced /ˌθɜːməʊɪˌlɛktrə(ʊ)ˈməʊtɪv ˈfɔːs/, and in American English it is pronounced /ˌθɜːrmoʊɪˌlɛktrəˈmoʊtɪv ˈfɔːrs/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: THERMO (heat) + ELECTRO (electricity) + MOTIVE (causing motion) + FORCE (driving power). Heat creates a motivating electric force.
Conceptual Metaphor
A 'thermal pressure' that pushes electrons, converting a temperature slope into an electrical push.
