Kilowatt (symbol: kW) is a unit of electric power. In this video we discuss how it work and its purpose to understand how electricity works. Ohm's law, taken as C = E, gives as values for current, C and E, and for electro- motive force C R. In these formulas, C represents current strength, R represents resistance and E … You can compare this to how fast water is flowing out of a water pipe. Voltage explained. Power: Definition For those who are keeping track, one watt is equivalent to electricity flowing at a rate of one joule per second in the metric system, which is also equivalent to 3.4 Btus per hour. The conversion is that one horsepower = 756 Watts. By implementing the Watt-hour meter, we can know how much amount of electrical energy is used by a consumer or a residence or an electrically powered device or a business. In 2010, the average US power use was 3.3 terawatts, or 3,300,000,000,000 watts. The electric power in watts produced by an electric current I consisting of a charge of Q coulombs every t seconds passing through an electric potential difference of V is It is named in honour A horsepower is a unit of power. Learn a new word every day. The word "per" means "divided by", so power = energy ÷ time. W Electricity An SI-derived unit of power equal to one joule per second. Electricity definition is - a fundamental form of energy observable in positive and negative forms that occurs naturally (as in lightning) or is produced (as in a generator) and that is expressed in terms of the movement and interaction of electrons. Watt-hours are a measurement of energy, describing the total amount of electricity used over time. In the electric power industry, megawatt electrical (abbreviation: MWe or MWe) is a term that refers to electric power, while megawatt thermal or thermal megawatt (abbreviations: MWt, MWth, MWt, or MWth) refers to thermal power produced.
