Definition of "Joule" |
Joule (abbreviated J): A measurement of energy or work. In mechanical systems, it's the a force of one newton, moving an object a distance of one meter. In electronics, it's the same amount of energy, in electrical units. One joule is one watt of power, applied for one second (a watt-second); or a coulomb of electrical charge raised to a potential of one volt. / The work done by a force of one newton acting through a distance of one meter. / SI unit of work or energy. One joule is defined to be the work done by a force of one newton acting to move an object through a distance of one meter in the direction in which the force is applied. / The joule, symbol J, is a derived unit of energy, work, or amount of heat in the International System of Units. It is equal to the energy expended or work done in applying a force of one newton through a distance of one metre. / The joule, symbol J, is a derived unit of energy, work, or amount of heat in the International System of Units. It is equal to the energy expended (or work done) in applying a force of one newton through a distance of one metre (1 newton metre or N·m), or in passing an electric current of one ampere through a resistance of one ohm for one second. / A type of semiconductor material used in manufacturing blue LEDs and other electronic devices. GaN semiconductors are the key to the LED lighting revolution. / the unit of work and energy. |
