Joule to all other Energy conversions
Joule
Joule is derived as unit of energy. 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.
Definition in formula:
J= kg.m2/s2 = N.m = pa .m3 = W.s = C.V = Ω.A2.s
One joule can also be defined as the following:
- The work required to move an electric charge of one coulomb through an electrical potential difference of one volt, or one coulomb-volt (C.V). This relationship can be used to define the volt.
- The work required to produce one watt of power for one second, or one watt-second (W.s) (compare kilowatt-hour – 3.6 megajoules). This relationship can be used to define the watt.
The joule is named after James Prescott Joule. As with every SI unit named for a person, its symbol starts with an upper case letter (J), but when written in full it follows the rules for capitalisation of a common noun; i.e., "joule" becomes capitalised at the beginning of a sentence and in titles, but is otherwise in lower case.
