Care to participate? ;-) Well, yeah, except that it's so simple to "explain away" by just saying that you're not paying for the electrons themselves that are just passing through, but the energy required to get them to do that passage. They've got the motor, you've got the wagon. The electrons are just a medium, conceptually indistinguishable from the way a V-belt transfers energy. I've said this in other FUs kinda ad nauseam, tonight. :-) Thanks, Rich |

Big deal. All they've got to do is pull some carbon rods out of a pile of radio-active crap and the job's done.

writes: 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? Simple. Electrons come into your house (supplied by the utility) and then they go back out. You don't buy them - you just pay rent for the time you have them. 73 de Jim, N2EY |

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 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. Yes please, guided energy!. It seems fathomable and sits easily amongst waveguides, aerials, lightbulbs and triphasic conduit. Electrons have a bit of weight. If you spin a metal disc at the power station fast enough, then all the electrons in it should centrifuge out and crowd towards the outer edge leaving no electrons in the middle. The electrons aren't happy being herded onto the outer rim and really just want to hang out and chew the cud. The potential to do work has thus been stored, just like in a flywheel. Paul switches on his TV and gives them a route back to the disc centre. The stored disc energy is immediately translated in his TV to heat, light and sound as the electrons all work through to become nonentities again. The power station people don't like this as all their patiently herded electrons have escaped, the disc has slowed a tad and they have to raise more steam to maintain speed and herd more electrons. Hence will charge Paul handsomely for his profligacy. Dunno what happens in a spinning capacitor with diode connected plates though :-) regards john |
