(thermodynamics) The cycle for the air engine proposed by Joule. In it air is taken by a pump from a cold chamber and compressed adiabatically until its pressure is equal to that of the air in a hot chamber, into which it is then delivered, thereby displacing an equal amount of hot air into the engine cylinder. Here it expands adiabatically to the temperature of the cold chamber into which it is finally exhausted. This cycle, reversed, is used in refrigeration.

(physics) A unit equal to a joule multiplied by a second, used to measure action or angular momentum.

plural of joule-second

A small, low-cost self-oscillating voltage booster, typically used for driving small loads.

Heat produced by the passage of an electric current through a conductor.

plural of joule thief

plural of Joule-Thomson effect

(thermodynamics) The temperature change of a real gas or liquid (as differentiated from an ideal gas) when it is forced through a valve or porous plug while kept insulated so that no heat is exchanged with the environment.
