Joule

- Noun

A unit of work which is equal to 107 units of work in the C. G. S. system of units (ergs), and is practically equivalent to the energy expended in one second by an electric current of one ampere in a resistance of one ohm. One joule is approximately equal to 0.738 foot pounds.

  • Joule

    The joule (/dʒaʊl, dʒuːl/ jawl, jool; symbol: J) is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre (1 newton metre or N⋅m). It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889).

  • Joule thief

    A joule thief is a minimalist self-oscillating voltage booster that is small, low-cost, and easy to build, typically used for driving small loads. This circuit is also known by other names such as blocking oscillator , joule ringer, vampire torch.

  • Joule expansion

    The Joule expansion (also called free expansion) is an irreversible process in thermodynamics in which a volume of gas is kept in one side of a thermally isolated container (via a small partition), with the other side of the container being evacuated. The partition between the two parts of the container is then opened, and the gas fills the whole container.

He then undertook post-doctoral work at with Professor Richard K. Hill at Princeton University and Professor Carl Djerassi at Stanford University. Then in 1963 he joined the academic staff of the Chemistry Department at the University of Manchester, where he is currently a Professor. In 1996 he received an RSC Medal for Heterocyclic Chemistry.

  • Optimal Energy Joule

    Joule was an electric five seat passenger car by Optimal Energy, a South African company based in Cape Town. According to the company, it was to have a nominal driving range of 150 km and a top speed of 135 km/h. Designed to achieve a Euro NCAP 4 star safety rating, it complied with the stringent EU standards. It was never released commercially; production ceased in April 2012, and in June 2012 Optimal Energy announced its intention to close down.
