Well, you have 'em in your house whether they're being pumped around, or not. It's more like a turnpike - you pay for the amount of distance driven, times the number of vehicles that you drive. Doesn't matter whether you're driving north, south, or north-and-then-south again. You drive, you burn gas, you pay the toll. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

The power company run a line to my house. They supply me with electricity. This amounts to a 230V, 65A facility at the distribution board in a cupboard under the stairs. I run all my stuff from that board. The board contains several RCBOs that trip-out in the event of any leakage current being sensed. If current in = current out; they're happy and won't trip. Because they don't trip out, I conclude I don't use any current. Two things flow along wires: charge and energy. The energy flows fast, while the charges flow slowly. The charges flow in a complete circle (you don't use any up,) while the energy is absorbed by your appliances. OK, here's the big question: which one is the electricity? If an electric current is a flow of electricity, then "electricity" is not energy, and the utility companies neither produce nor sell any electricity. It all depends on how we define the word "electricity." And unfortunately the reference books don't agree with each other. Some books follow the scientists of old, and define electricity as charge (so a quantity of electricity is measured in coulombs, and a flow of electricity is measured in amperes.) Other reference books ignore that definition, and instead they insist that electricity is energy... so a flow of electricity is measured in watts, not amps. The voltage supplied is 230VAC RMS. Since this is alternating between equal positive and negative half-cycles, the average level of this voltage supply is zero. I use no current and they effectively supply no voltage. Why do I get billed for electricity usage when I clearly can't have used any? The path for electric current is CIRCULAR. For every bit of charge that the electric companies force into your appliances, an equal amount of charge goes back out through the other wire. The current is also oscillating (the charges don't actually flow, instead they vibrate back and forth over extremely tiny distances.) On the other hand, the path for electrical energy is one way. The electric companies send electromagnetic energy over enormous distances. It's this energy which your appliances consume. Unfortunately for our definition of "electricity," this energy is composed of electric and magnetic fields, and it travels in the space surrounding the wires. Do we really want to state that electricity is made of EM fields? Do we really want to say that no electricity travels inside of wires, but instead it travels in the space outside? If we say that electricity is a form of energy, that's the same as saying that electricity is just some travelling waves of electromagnetic field. Possible solution: never use the word electricity at all. If you want to say that electrical energy flows along a circuit, then say exactly that. If you want to talk about flows of charge, then speak of charge and not "electricity." As long as we never mention the word "electricity," then amperes and watts are no longer mistaken for each other, and we can get on with explaining the joules and coulombs in ways that make sense. |

If you multiply negative voltage by negative current you get positive power. Sorry, Don, you obviously haven't thought this through. Since *all* their current is returned, I cannot have used *any* of it. Whatever the voltage might be, multiplying it by zero Amps still gives zero power! Paul, perhaps you should be a politician... What you are charged for is the use of the current as it flows through your appliances etc. Because the current flows in your appliances it places a load on their generating plant. Because millions of houses are also doing the same thing at the same time the load on the generating plant is enormous and in order to supply the large amount of current required by all users (yes, even though they do get it back in the return feed), the generating plant has to be enormous itself. Now, power stations aren't something you pick off a tree, they have to be built and maintained and they consume "energy" in order to be able to generate the large amount of current which flows. Now even a dill can see that the cost of building and running the plant has to be paid for and the cost of doing this is usually amortised over a period of 15 or 20 years and after that it is pure profit. So you are paying for the current which flows through your systems to generate heat, cool and cook your food, run your stereo etc, etc. Now despite your fallacious arguments about supply voltage summing to zero and the supply authority getting all their current back after having gone through your house, you can't argue that you shouldn't be charged purely for no other reason than the law stating the conservation of energy. "Energy can neither be created nor destroyed, but may only be changed from one form to another." The supply authority is changing one form of energy to another in order to generate electrical energy and you are changing the energy they supply into other forms required to generate heat, cooling etc in your household. I can tell you this, converting energy from one form to another doesn't come free and not even a politician would be stupid enough to believe that it does. Anyway - are you cleaning and refurbishing those amps before you give them back? Why should I? That's *their* job. I pay enough! They wear out, you know. You mean they like lose their charge after a while? That would make sense as I've found as years have gone by, I've had to turn the heating up more and more. The thieving *******s! |

wrote: For a purely resistive load, since P = I²R, the sign of the current going into the load gets squared, so that when it goes in negative it comes out positive. Seems like there's an opportunity for free energy kooks there. Put positive and negative current in alternately, averaging zero, but get all positive power. :-) |

Back in my days in the old country, I used to walk 5 miles through snow and sludge in the middle of winter to go to the next village to buy a couple of batteries so that my father can listen to his nightly stories on our wireless. :P -- Alf Beta. |
