What is Diathermous? Definition, Examples, and Applications

Diathermous (di-ath-er-mous) is an adjective used to describe something that is capable of generating or transmitting heat, especially through electrical resistance. The term is derived from the Greek words "dia" meaning "through" and "thermos" meaning "heat".

In science and engineering, diathermous materials are those that have a high electrical resistance and therefore generate heat when an electric current flows through them. Examples of diathermous materials include metals such as copper and silver, as well as certain types of ceramics and polymers.

Diathermous materials are used in a variety of applications, including heating elements, electrical contacts, and thermoelectric devices. These materials can convert electrical energy directly into heat energy, which can be useful in a wide range of industries, from cooking and heating to power generation and medical devices.
