  Joule - Wikipedia, the free encyclopedia
The joule (symbol: J) is the SI unit of energy, or work with base units of kg·m²/s² (N·m).
The joule is a derived unit defined as the work done or energy required, to exert a force of one newton for a distance of one metre, so the same quantity may be referred to as a newton metre or newton-metre with the symbol N·m.
Its value was found by James Prescott Joule in experiments that showed the mechanical energy Joule's equivalent, and represented by the symbol J. The term was first introduced by Dr. Mayer of Heilbronn.

 James Prescott Joule - Wikipedia, the free encyclopedia
The SI unit of work, the joule, is named after him, and is pronounced to rhyme with "tool." He worked with Lord Kelvin to develop the absolute scale of temperature, made observations on magnetostriction, and found the relationship between the flow of current through a resistance and the heat dissipated, now called Joule's law.
Joule was influenced by the thinking of Franz Aepinus and tried to explain the phenomena of electricity and magnetism in terms of atoms surrounded by a "calorific ether in a state of vibration".
Joule was a pupil of Dalton and it is no surprise that he had learned a firm belief in the atomic theory, even though there were many scientists of his time who were still skeptical.

 sociology - Joule
The joule (symbol J, also called newton meter, watt second, or coulomb volt) is the SI unit of energy and work.
One joule is the work required to exert a force of one newton for a distance of one metre, so the same quantity may be referred to as a newton metre or newton-metre (also with meter spelling), symbol N·m or N m.
One joule is also the work required to move an electric charge of 1 coulomb through an electrical potential difference of 1 volt.

 James Prescott Joule
Joule soon began to conduct independent research at a laboratory built in the cellar of his father's home.
Joule was extremely involved with this work, and between 1837 and 1847, he established the principle of conservation of energy, and the equivalence of heat and other forms of energy.
As is characteristic of many researchers, Joule's accomplishments were not limited to those things we today associate with the word "research." Much of what comes from experimental investigations results in practical devices and new technologies.

Joule was the second son of a wealthy brewer, which meant he had the means to devote himself to a life of research.
Joule was almost a fanatic on the subject of measurement, and even on his honeymoon he took time out to devise a special thermometer to measure the temperature of the water at the top and bottom of a scenic waterfall his wife and he were to visit.
Joule was elected to the Royal Society in 1850, received its Copley medal in 1866 and was president of the British Association for the Advancement of Science in 1872 and in 1887.

 Joule and the Conservation of Energy
James Joule was born in 1818, the second son of a prosperous brewer in Manchester, England.
Joule also calculated that the water just beyond the bottom of a waterfall will be one degree Fahrenheit warmer than the water at the top for every 800 feet of drop, approximately, the kinetic energy turning to heat as the water crashed into rocks at the bottom.
Joule’s work was so impressive that his provincial origins were forgiven, and by the late 1840’s he was regularly presenting papers to the British Association and the Royal Society.

 James Joule
Joule had the idea that he could use the electric motor to convert the family brewery from steam power to electric power.
Around 1845, he was able to demonstrate in a paddle-wheel experiment, which involved the shaft and paddles being driven by a falling weight suspended from a pulley, that the same amount of work, however done, always produced the same amount of heat.
Joule and his wife had three children, Benjamin Arthur (b.1849), Alice Amelia (b.1852) and a son who died in 1854 along with his wife.

Joule is that product: it is the culmination of over four years of research, and it incorporates technologies gleaned from Valpar's twenty-five years of experience and the expertise of nine professional providers of FCEs, each with many years of relevant experience.
Joule has an initial (expandable) list of twenty job-specific FCEs with their own special mix of protocols that are selected to match demands of major job categories, such as materials handling, construction, and food service.
The Joule approach is to administer all three core lifts (waist to waist, waist to mid-shin, waist to eyes) at the same time; all three lifts are performed simultaneously, alternating the lifts after one time at each weight level.

 Joule Rating
The manufacturers that do utilize nonlinear components and advertise joule ratings, tend to calculate their joule rating by virtue of summing the highest value in the scale of the joule values for that particular nonlinear component.
The rating, in joules (watt-second), is the maximum allowable energy for a single impulse of 10/1000 m s current waveform with continuous voltage applied.
Whether or not the joule rating is an effective means of measuring a surge device’s energy absorption capability is up for personal speculation and evaluation, but one must remember that joule rating is not criteria defined by NEMA LS1 or ANSI/IEEE as criteria deemed essential for a surge suppressor.
