The unit of measurement for electrical power, named after James Watt, an 18th century Scottish engineer One watt of power is dissipated when a voltage of one volt is applied across a load of one ohm resulting in one ampere of current in the circuit See POWER
A watt is a unit of measurement of electrical power. Use a 3 amp fuse for equipment up to 720 watts. a 100-watt lightbulb. British engineer and inventor who made fundamental improvements in the steam engine, resulting in the modern high-pressure steam engine (patented 1769). An International System unit of power equal to one joule per second. See table at measurement. a unit for measuring electrical power (James Watt)
The electrical unit of power The rate of energy transfer equivalent to 1 ampere of electric current flowing under a pressure of 1 volt at unity power factor
A measure of electrical power or amount of work done in a unit of time and equal to the rate of current flow (amps) multiplied by the voltage of that flow (volts) One amp of current flowing at a potential of one volt produces one watt of power
Unit of electrical power required to do work at the rate of one joule per second One watt of power is expended when one ampere of direct current flows through a resistance of one ohm The power capability of amplifiers and loudspeakers is given in watts, which relate to both the voltage driving the system and current handling capabilities of the devices
In the International System of Units, the derived unit of power; the power of a system in which one joule of energy is transferred per second. Symbol
A common unit used in measuring power Power is defined as the flow of energy over time A watt is equivalent to 3 41 Btu/hour or one joule per second Where an "e" follows the unit (as in kwe or Mwe), the watt is in the form of electrical energy Where a "t" follows the unit (as in kwt or Mwt), the watt is in the form of thermal energy
A unit of electric power The watt is the power required to do work at the rate of one joule per second
The electrical unit of power or rate of doing work The rate of energy transfer equivalent to one ampere flowing under a potential of one volt at unity power factor
A unit of electrical power One watt is equivalent to the power represented by one ampere of current flowing through a load with a voltage drop of one volt in a dc circuit
The quantitative unit of measurement of actual power Actual power in an AC circuit is the measurement of the effective energy available for doing work, and is normally less than apparent power (volt-amperes) because of power factor considerations Watts may be measured directly, by means of a wattmeter, or may be calculated by multiplying volt-amperes by the power factor of the equipment
A meter which measures, and registers, the amount of electricity consumed in a circuit; especially one connected to a domestic power supply for the purpose of billing
a British engineer who made important improvements to the steam engine. The measure of electrical power, the watt, is named after him (1736-1819). born Jan. 19, 1736, Greenock, Renfrewshire, Scot. died Aug. 25, 1819, Heathfield Hall, near Birmingham, Warwick, Eng. Scottish engineer and inventor. Though largely self-taught, he began work early as an instrument maker and later as an engineer on the Forth and Clyde Canal. Watt's major improvement to Thomas Newcomen's steam engine was the use of a separate condenser (1769), which reduced the loss of latent heat and greatly increased its efficiency. With Matthew Boulton he began manufacture of his new engine in 1775. In 1781 he added rotary motion (a so-called sun-and-planet gear) to replace the up-and-down action of the original engine. In 1782 he patented the double-acting engine, in which the piston pushed as well as pulled. This engine required a new method of rigidly connecting the piston to the beam, a problem he solved in 1784 with an arrangement of connected rods that guided the piston rod in a perpendicular motion. His application of the centrifugal governor for automatic control of the speed of the engine (1788) and his invention of a pressure gauge (1790) virtually completed the Watt engine, which had immense consequences for the Industrial Revolution. He introduced the concept of horsepower; the watt, a unit of power, is named for him
born April 13, 1892, Brechin, Scot. died Dec. 5, 1973, Inverness Scottish physicist. He began as a meteorologist working on devices for locating thunderstorms. As head of the radio department of Britain's National Physical Laboratory (1935), he worked on aircraft radio location and could locate planes at a distance of about 80 mi (110 km) by beaming radio waves at them, receiving reflections of the waves, and calculating distance by elapsed time. This led to the design of the world's first practical radar system, a vital element in the defense of Britain against German air raids during World War II. His other contributions include a cathode-ray direction finder used to study atmospheric phenomena, research in electromagnetic radiation, and inventions used for flight safety

Standard measure of electricity Amps X Volts = Watts A watt takes into account the amperage and voltage together 1300 watts is the highest legally in the US for one appliance on 110 volts
Unit of electrical power derived from the current (or "quantity" of electricity) multiplied by the voltage (or "pressure" at which the current is delivered) Stage lighting equipment is rated in Watts (or Kilowatts - 1 kW being equal to 1000W) This refers to the amount of power required to light the lamp A higher wattage lamp requires more power and gives a brighter light output
A quantitative measurement of electrical power Watts are calculated by multiplying volts times amps Using a liquid analogy, watts are similar to liquid flow such as liters or gallons (watts = volts x amps)
A unit of electrical power derived from the current (or quantity of electricity) multiplied by the voltage (or pressure at which the current is flowing)
