I really like the look of mini-pendant lights. The more lights, the better! My vision was to arrange about 20 of them in a line, scattered about in an semi-organic pattern. I needed to construct a mount and figure out a way to convert the line voltage to 12 volts to power the 10 watt lamps. I'm not much of an electrician, and I was trying to keep the project around $300, so I figured it was best to cannabilize several existing low-voltage, mini-pendant lamps. IKEA hooked me up with three KRYSSBO lamps that came with some nice looking, glass pendants, bulbs, and the necessary transformers. I grabbed a spool of speaker wire, some wood, and I was set.

That's exactly the what I had in my mind with the smallest expense
I love you for this
Thanks a lot!

BTW--A great way to both protect AND cap wired connections is with a high-temp hot glue gun! I I tried it on a whim when I was installing my in-wall surround-sound system (which I installed in a two-story living room). I had so many connections to bridge, and didn't want to have to try to deal with soldering the bridges when they are 20 feet of the ground), and needed the bridges to be as flush as possible, since I was installing them in a shallow groove in the drywall--so capping each bridge was out of the question.
It works so easily, and is much better than electrical tape or capping because it won't separate under strain. I have since used it on lots of electric circuits, and it's really a life-saver. I should probably do an instructable on it. :)

Current is the measure of flow of charge through an electrical device, while Voltage is the force that tends to move the electrons. If we think of electricity as water, then Apmeres would be similar to gallons per minute (GPM), and Voltage would be similar to pressure per square inch (PSI).
To the original question, it really depends on the number of lamps, what type of bulb, and what gage speaker wire you are using. The instructable shows the lamps wired in parallel, which means that each lamp receives the same ammount of Voltage, 115VAC in the US. The current flowing through the plug is the sum of the current used by each lamp.
A 60W bulb operating at 115VAC uses ~.52 Amps (Power = Voltage*Current, so 60W/115V = .52A). If you are using 6 lamps as shown here, with 60W bulbs, then the supply wire would need to carry 3.13 Amps. 12 lamps, 6.26 Amps.
To be on the safe side, go get some romex wire from your local hardware store, as that is what is most likely supplying your electrical outlets anyway.
I see you're new to Instructables. This is a really well documented Instructable for the first time, so really nice job!
Hope to see much more equally-awesome work from you in the future =).
