Electrics Tech request

Is anyone here particularily knowledgeable about electricity? I understand electronics pretty well but the actual dynamics of elctricity have usually passed my by.

So, could someone write a tech archive article discussing the relationship between watts, volts and amps. How an oversupply of any of them work- ie what happens if you supply too many amps/volts to a unit, what you can and cannot do with a supply, how resistance works, how the more common electrical units in a car work- like relays, resistors etc. Also perhaps we could discuss how wire gauges are calculetad and how bigger and smaller diamaters affect the cpacity of electricity. jujst general stuff really.

alternatively if anyone konws any good online articles then that would be great- the ones i can find are either extremely simple, or assume you have a certain amount of knowledge.

it's amazing that i can build computers but haven't got a clue about what powers them!

It's a sign of the times - come Armageddon the guy who can rig up a wind genny, a few lights and a motor will be worth more than all the computer teccies put together!

OT

On a bright note, we're all gonna starve anyway as nobody can handle where meat actually comes from!! :o

I don't understand how you can "understand electronics pretty well" but not have an understanding of basic electric theory. I don't think you can have one without the other!

Or do you mean you know how to use / interconnect electronic things? I suppose you could get a fair way with digital electronics without much understanding of electrics.
