Talk:Electric power industry

message: 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
:Note: the above editor has now added those equations to Electric power, so all is well. --Heron 17:35, 14 July 2006 (UTC)

message: 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.
:Caution, errors above.  Power is measured in watts, or megawatts (MW) if you prefer.  Load is usually a resistance, or a measure of a receiving electrical device's capacity to absorb electrical energy/power.  Resistance has units of volts per ampere, or volt-sec/coulomb.  A key point in computing the actual power delivered during any sufficiently small interval of time is knowing the actual voltage and the actual current during that interval of time.  For a resistive load, the voltage and current cycles are in phase, both going to zero twice per cycle at exactly the same instant in time.  So, during the instant of the "zero crossing" no power is delivered to the load, since power delivered is the product of current and voltage.  As for the analogs, water pressure is the analog of voltage. The amount of water passing through a pipe, or flow rate, (gallons per second) is the analog of current.  Water is the analog of coulombs.  Electrical power is therefore the analog of a quantity proportional to the product of water pressure and flow rate (call it hydrolic power), and really only of interest in devices designed to accept and convert this power to some other form of power, like a hydrolic motor.  And finally, electrical energy is the analog of "hydrolic energy," the product of the hydrolic power and the time over which that hydrolic power is delivered. blackcloak 17:34, 22 May 2007 (UTC)

message: 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)
thread_title:  Remove merge tag 

message: 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)
thread_title:  Ferranti 

message: 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). 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.

message: Isn't the electrical industry more than just power generation and distribution? Doesn't it include stuff like appliance production, consumer electronics, electrical machines for industry etc.? -- 92.230.210.92 (talk) 15:18, 17 February 2013 (UTC)

message: Greetings Wikipedians! I added language which explains the industry restructuring which took place in the U.S. beginning in the 1990s. Cordially, BuzzWeiser196 (talk)
