In most places in this article we're talking about electric ENERGY, not electric power. Energy is what electric companies sell, while "power" has identical meaning to "flow rate of energy." If it was water, would we talk about the supply of water, or the supply of "flow?" Watts are the flow rate, JOULES are what is flowing. For so many years we've been wrongly saying "Electric Power companies" rather than "Electric energy companies" that now the correct terminology sounds weird, while the wrong words sound safe and normal.
The first poster on this page gave the reason: electrical power is a term in electrical engineering and physics first. It's colloquial miss-use in North America for electricity delivered by a power distribution system should not be allowed to push the proper meaning to the background. Of course a disambig link would go at the top. DV8 2XL 00:46, 29 November 2005 (UTC)
I think that the term "electric power" is commonly used in a very correct manner. The average person knows what a 60 watt light bulb is. He understands that leaving it on for a longer period of time uses more "electricity", and more money, than using it for a short period of time. He understands that a 1200 W hair dryer uses "electricity" very fast and should not be turn on for very long. Electric utilities build power plants based on rated MW, not so much MWh. Energy is important as well, but don't dismiss the importance of power. Whquaint 03:09, 22 June 2006 (UTC)
"Capacitive circuits cause reactive power with the current waveform leading the voltage wave by 90 degrees, while inductive circuits cause reactive power with the current waveform lagging the voltage waveform by 90 degrees" You meant to say perhaps that inductive circuits cause direct power???
As a result of reading through this article I have found it to be an inaccurate representation of the historical facts, something which is a Wikipedia issue of accuracy and credibility. There is also a level of bias in the way it is written, with no mention of Edison's excellent work undertaken in the UK in which his Holborn Viaduct Power Station was working earlier than his Pearl Street Power Station. Accordingly I have corrected this and put the correct chronological order of electricity supply scheme commissionings. Given the level of discussion as to the choice of title I would suggest that it is changed to Electricity Supply Industry as a more accurate representation of what it is meant to describe. Also provided are some references. aquizard 19:45, 29 December 2006 (UTC)
Under Ohms law there are three equations to calculate power in a circuit.
P= IV -- Example: 2 amps * 12 volts = 24 watts
P = I^2 * R -- Example: (2 amps * 2amps) * 6 ohms = 24 watts
P = V^2 / R -- Example: (12 volts * 12 volts) / 6 ohms = 24 watts
The term 'power' is mis-used generally in this entry, notwithstanding the common usage of the word 'power' by electricity consumers. What is being consumed is electric energy, and most billing is based on the amount of energy passing through the customer's meter. It's true that electric 'power' is often also a basis of a different type of billing, but this is generally reserved as a proxy by utilities to cover the fixed costs of providing sufficient scale of equipment to service the maximum number of Amps supplied to the consumer, and is typically applied only to larger commercial or industrial consumers. This load is equivalent to the 'power' provided to the customer, and is measured in MW (often with a correction to compensate for the customer's inductive load). Let's be consistent with physics: power (or load) is measured in MW, and is equivalent to water pressure in a pipe; energy is measured in MWh, and is equivalent to the amount of water that passes through the pipe.
Also, let's not forget that although most residential customers think they are consuming 'electricity', they are, in fact, consuming electrical energy.
No discussion of the reason to merge on the talk page. No activity since then. Topics clearly different - "electricity" about the physical phenomenon, "electric power" about what we do with it. I'm removing the merge tag. -- Wtshymanski 15:24, 9 September 2007 (UTC)
I'm no expert in this subject but I'm surprised to find no reference to Sebastian de Ferranti in the early history here. For example his Deptford Power Station, an early large-scale AC plant, seems to be quite a significant milestone. Pterre ( talk) 12:44, 29 April 2008 (UTC)
Reworded history section ( dif) because it described AC as "Tesla's alternating current system" and made claims such as Tesla designed the generators at Niagara Falls (that was actually George Forbes [1]). It could also use a better referenced history on AC as to who did what in the US and Europe. There were many who developed AC in Europe and the US.
