I have a table lamp that takes a three-way bulb. The lamp does not have a standard switch; rather, you adjust the intensity of the light and turn the lamp on or off by tapping the metal base one, two, or three times. Recently the lamp's bulb burned out and I replaced it with the same kind of three-way bulb that was in there before. But now tapping the base produces no effect - the lamp stays on its brightest setting and can only be turned on and off by plugging it in or unplugging it. What happened, and can it be fixed? I've only had this lamp for about six months, and it wasn't cheap. I've tried various different bulbs, but nothing seems to work.

In the rain at my outdoor subway station in Brooklyn this morning, I observed once again a bizarre phenomenon: water drops appear to drip upwards from the third rail to the wooden cover above it. My wife saw this too. What's going on?

I have a friend visiting me from the UK that is looking to buy a Nintendo DS while he is here to bring back home. Does he need to buy a converter to use with the included power adaptor, or does he need to buy a 240 charger back home? Will the US adaptor work with UK outlets? [more inside]
Since December 2006, my electricity bill has shown at least a 1,000 KWH increase over the same period a year ago. We haven't purchased any new appliances, or done anything appreciably different. This month, we didn't use our air conditioning/heating unit at all, and our bill still came in 25% higher (500 KWH) than a year ago. We're at a loss. What could be the reason? We ordered a Kill-a-watt, but till it arrives, we are trying to figure it out. Any thoughts? [more inside]
This product claims to save electricity through some sort of voltage and current regulation. This raises my suspicions, but there might be some explanation for it I've missed, probably down to some peculiarity of mains electricity?

I have a ten-year-old Sony TV that's on the fritz. It's a good enough second set that I'd like to save it if possible, but it's also big enough that it's going to be a pain to haul in to the shop for an estimate. If I decide to pop the case and dive inside for a quick sanity check, what do I need to do to avoid electrocuting myself in the process? [more inside]

New York City residents: Have you switched from Con Edison to another electricity and/or gas supplier under deregulation? If so, have you seen a significant difference in your bill, and how is the new provider's customer service? I'm trying to decide whether to switch to another provider (Econnergy, Energetix, etc.) for electricity, gas, or both.
I just picked up a 1000W step-down converter (220V-110V) to power a receiver after a 750W exploded in a blaze of glory when I turned it on one morning. I'd very much like to avoid this kind of thing again. So my question is, is it relatively safe to keep step-down converters turned on at all times? If so, will it constantly be using 1000W of power even when the receiver is turned off? I've heard differing opinions but found no definitive answer on the interwebs. Related, is it true that you should always have something plugged into the converter when it is turned on?
I have two Nokia mobile phones - one purchased in the US and one that I've purchased here in Indonesia, both with their own similar-looking chargers (though with obvious differences on the plugs). Can I charge the Indonesian phone in the US on the US charger? [more inside]

Voltage converter / inflating an air mattress to be used in Italy: My friend, a sculpture instructor in Florence, Italy, is putting us up and guiding us around the city. Very cool.

After a last minute sale of my condo, the deal on the house I bought closes on Thursday. I need to arrange for utilities, insurance, and some repairs, and have next-to-no time to do research. If you have a satisfactory provider of any of these things and said provider's services are available to a Torontonian, recommend away! And of course I'll think of you all when I'm doing my happy dance on my rooftop terrace;-) [more inside]

I live in a hundred-year old house (in Los Angeles, no less!) that has limited electrical outlets. I have unlimited (it seems) electronics - three computers, monitors, two laser printers, two air conditioners, electric heater (in the winter), etc. The house was upgraded from old-style fuses to circuit breakers a few years ago. It is a rental so I am not able to do any upgrades. None of the wall outlets are three prong, so I am using adapters. In the summer, my office is just overdone with things drawing power - all three computers, the printers, AC, and probably 20 (or more) smaller items - cell phone, postage scale, radio, etc....

Physics filter: The original fuse for an Ikea lighting system was rated for 6.3A and 250V. After a power surge, I noticed that the fuse had been toasted. Upon visiting 3 hardware stores, the best I could find was a similar fuse rated for 3.15A and 125V. Since V=I*R, it follows that the resistance is identical when the original fuse is compared with the replacement. Does this mean that these fuses are functionally equal?
