Joule's law, also known as the Joule-Lenz law or the Joule-Thompson effect, refers to the principle that describes the relationship between electric current and heat generated in a conductor. There are a number of synonyms for this law, which can be used interchangeably depending on the context. Some common synonyms for Joule's law include Ohm's law (which describes the relationship between voltage and current in a conductor), the law of thermodynamics (which describes the movement of heat energy between multiple systems), and the principle of conservation of energy (which states that energy cannot be created or destroyed, only converted from one form to another). Other related terms include energy transfer, thermal conductivity, and electric resistance.
