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! |
