joule

 

[ dส’uหl ]

Noun
Context #1 | Noun

unit of energy

The joule is the SI unit of energy. It is defined as the energy transferred when one newton of force is applied over one meter in the direction of the force. One joule is equivalent to one watt-second, and it represents the energy used when an electrical current of one ampere passes through a resistance of one ohm for one second. The joule is named after the English physicist James Prescott Joule, who contributed significantly to the understanding of energy and thermodynamics.

Synonyms

energy unit, watt-second.

Examples of usage

  • The light bulb consumed 60 joules per second.
  • This battery has a capacity of 1000 joules.
  • The work done is 50 joules when lifting the box.
  • Energy transferred equals 100 joules in this process.

Etymology

The term 'joule' originates from the name of the English physicist James Prescott Joule, who lived from 1818 to 1889. He was a pioneering figure in the field of thermodynamics and is best known for his experiments on energy conservation and the transformation of heat. The joule was adopted as a standard unit of energy in 1889 by the International Electrical Exhibition in Paris, recognizing Joule's significant contributions to science. The name serves to honor his work on mechanical energy and heat, notably the Joule's law, which states that the heat produced is proportional to the current squared, resistance, and time. Over time, the joule has become an essential unit in various scientific fields, including physics, chemistry, and engineering, and is widely used in calculations involving energy, work, and heat.
