DEFINITION: Also see current, voltage, resistance,and Ohm's Law.Electrical power is the rate at which electricalenergy is converted to another form, such as motion, heat, or an electromagnetic field. Thecommon symbol for power is the uppercase letter P. The standard unit is the watt,symbolized byW. In utility circuits, the kilowatt (kW) is often specified instead;1 kW = 1000 W.One watt is the power resulting from

POWER SUPPLIES DEFINITION (continued): … an energy dissipation,conversion, or storage process equivalent to one joule per second. When expressed in watts, power is sometimes called wattage. The wattage in a direct current (DC) circuit is equal to the product of the voltage in volts and the current in amperes. Thisrule also holds for low-frequency alternating current (AC) circuits in which energy is neither stored nor released. At high AC frequencies, in which energy is stored and released (as well as dissipated or converted), the expression for power is more complex.In a DC circuit, a source of E volts, deliveringIamperes, produces P … Power Supplies definition sponsored by SearchCIO-Midmarket.com, powered by WhatIs.com an online computer dictionary
