Meaning of joule
joule (n)
a unit of electrical energy equal to the work done when a current of one ampere passes through a resistance of one ohm for one second
English physicist who established the mechanical theory of heat and discovered the first law of thermodynamics (1818-1889)
joule (n.)
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 Sentence Examples
- One joule is the equivalent of one newton meter, representing the energy required to exert a force of one newton over a distance of one meter.
- The joule is the SI unit of energy, work, and heat, and is named after the English physicist James Prescott Joule.
- A joule can also be expressed as a watt-second, as one joule is the energy expended when one watt of power is applied for one second.
- The total energy of a system is measured in joules, and this energy can be transferred or transformed from one form to another.
- In the context of electricity, a joule is the energy dissipated when one ampere of current flows through a resistance of one ohm for one second.
