The process of joining two dissimilar metals together at a junction and applying heat to produce a transfer of electrons is known as what?

The process of joining two dissimilar metals together at a junction and applying heat to create a transfer of electrons is known as thermoelectricity. This phenomenon occurs due to the temperature difference across the junction of the two metals, facilitating the movement of charge carriers, which generates an electric current.

In practical applications, this principle is often used in thermoelectric generators and cooling systems, where heat is converted into electrical energy or vice versa. The basic concept hinges on the Seebeck effect, where a voltage is produced in response to a temperature gradient across two different conductive materials.

Understanding this process is essential for linemen, as thermoelectric devices may be part of various electrical systems, and recognizing the behaviors of different metals when joined can aid in effective troubleshooting and maintenance.
