How do electric meters work?

How do electric meters work? How do they measure the amount of charge you used? I suspect they must know the amount of charge that enters the home, and then they have some way to measure the amount of charge that leaves the house, but I'm really not sure. [more inside]

Deregulation and Electricity: More than Just A Headache?

EnergyPurchaseFilter: What is the deal with non-regulated electric purchasing?

Free electricity!?

I've been living in my apartment since December, and I still haven't received an electric bill from ConEd. It was made clear that we had to sign up to receive power and we did that -- my wife called in, gave them her social security number, address, etc. Still, no bill. The meter man comes by every month and checks the meter. Still, no bill. [more inside]

Making the most from brook in back yard: waterwheel generator?

On our property there's a rather substantial brook running through it, which runs year round and doesn't freeze over. It's probably too wide for a traditional undershot waterwheel (at least 12 feet across at its most narrow), to supply some alternate power to our house, but maybe there's something else that could make the most of the constant flowing water?

Learning about electricity, the bright and colorful but not completely dumbed-down way?

I'm looking for a book that teaches electricity well. The Mims book definitely doesn't cut it - I want something more along the lines of "The Way Things Work" in clarity and accessibility, but I still want it to actually teach the underlying math; i.e., I want it to show me the material in pictures and equations.

Electrical arc photo identification needed.

Please help me find this great picture of electrical arcs. I saw this photo a while back. I'm pretty sure it was in a magazine. It was of a great big round room, with some sort of large apparatus, like a collider or something (it wasn't a collider I don't think). There were scaffolding and cat walks running everywhere. Lots of pipes and fittings. Everything was gold or copper or something. And the entire room is covered in arcs of electricity. Great big bolts running all around the room, with smaller and smaller branches and fingers breaking off to fill up every metal surface area with arcs. It was some sort of electrical discharge as a result of the experiment that was being run. I can't remember what it was, so I don't even know what to look for in Google. Any help would be appreciated. Even just a guess as to what the device was that would produce that, so I have a starting point to try and find it. Thanks.

How much does it cost to wash?

How much does it cost (or what is the amount of electricity / volume of water used) to do one full load of laundry, as an average. Or, how would I go about getting precise figures for this? I want to know how much too much we pay to operate the pay-per-load laundry machines in our new apartment building.

Getting shocked while ungrounded

Why is it that if I walk up and stick my finger in a wall outlet, I'll get shocked even though I'm not grounded? I can see getting shocked when standing barefoot on wet ground, but come on... on a floor wearing tennis shoes? How does that work?

efficiency and power consumption of computers

I have two computers, each with something like 350W power supplies. By keeping them on 24/7, am I consuming the equivalent of seven 100-watt light bulbs around the clock? What can I do (either software or hardware) to make my machines more power-efficient? Also - while I'm on the subject - does an incandescent bulb consume less when it's on a dimmer and that dimmer is turned down? [more inside]

OFF - HI - MED - LO

Just a stupid question that's puzzled me for years: Why is it that, on electric fans, the order of the settings on the switch is OFF - HI - MED - LO? I'm sure there's an electrical reason for this, but I don't know what it is, since I know nothing about circuitry. One would think that OFF - LO - MED - HI would make more sense. Can someone explain this to me?

Will I burn down my apartment?

I just replaced a burned out bulb in my overhead kitchen fixture. The bulb that burned out was a 60 watter. I only had a 100 watter on hand. I know I'm hastening fossil fuel depletion, but am I also causing a fire risk? What about ignoring the wattage recomendations in favor of higher watts in table lamps?

AC power

If I have AC power at 50Hz, does it mean my lightbulb is flickering 100 times a second and I just can't see it? Is this why, when passing a street light in a speeding train, it can appear as a series of dots in your vision?

What's causing my lights to pulse?
