FAQ

A wire has a resistance of 21.0 ohms. It is melted down, and from the same volume of metal a new wire is made that is three times longer than the original wire. What is the resistance of the new wire?

The resistance of the new wire is (in terms of its length, area resistivity); R2 = pL2/A2 And the resistance of the original wire is; R1 = pL1/A1 The ratio is;(resistivity will cancel because its the same for both situations) R2/R1 = L2A1/L1A2 given L2 = 3L1 R2/R1 = 3A1/A2 To find the new cross-sectional area ,require the volumes to be equal; L2A2 = L1A1 3L1A2 = L1A1 A2 = (1/3)A1 Sub this into the R2/R1 equation to get; R2/R1 = 9 R2 = 9R1 = (9)(21) = 189 ohms

Is it better to have a wireless internet connection or a wired connection for my ps3 online games?

Wired is much better, because it works faster, it's secure, far more reliable. The only downside of a wired connection is a necessity to mess around with cables. On the other hand, you do it only once. I'm using a wired connection.

I need the designations for the wires so I can splice in an amp.

Speaker wires: left front: (+) tan (-) gray right front: (+) lt. green (-) dk. green left rear: (+) brown (-) yellow right rear: (+) dk. blue (-) lt. blue Accessory power at radio for amp turn-on: yellow (only in 2003 and older; should be located next to orange constant power wire)

I need to wire a single 120v outlet from the 240v volt wire I use on my compressor. Im installing a 120v electric automatic drain valve on my large shop air compressor. The compressor is wired up with SJ00W 10-AWG, 4-wire power cable (red,green,black white wires). and is rated at 240v @ 15-amp(compressor not wire). The drain valve uses a normal house hold current wiring config. (black,white and open copper)The 240v power supply is the only supply I have near by, (two of them actually) Or I would just wire the automatic valve off an outlet and call it a day. So How do I wire a 120v 3-wire set up from the 240v 4-wire supply? Thanks

How To Wire 240v

I just learned how to do 3-way wiring, so that I can turn a light off from 2 different switches. My question is, how do I add another light to that mix, so that both lights come on/go off at the same time when I turn the switches on and off? (It's for a closet that has 2 lights in it that I want to come on/go off at the same time).

Very basically, you must have two wires going from light to light. A black wire and a white wire.( A bare copper wire should be included with the pair. It is a ground wire and grounds both light boxes together.) Back to the black and white wires. The black wire should be connected to the black switch leg wire at the first light box as well as to the first light fixture. The white wire is the neutral and should be connected to the white wire of both light fixtures. That's called a parallel connection. Just a note: There are several ways to wire three way switches, so my answer presumes there are two wires going from one of the switches directly to the light fixture. (A white wire and a black wire).

what size of wire should I use for my 1.5hp aircon, 220volt

#12 because it runs for 3 hours or more and if you get a larger one it will be cababile of running it

I have a Speedaire 4B234 its currently wire to 120V but keep flipping the breaker and I have a 240V in the garage so I want to wire it to that. I have 2 blue wires, 2 red wire, and 2 green wires but the green wires are hooked together. One blue wire goes to Line and the other to Motor and same thing with the red wires.

You cant run 220 into a 110v motor. Buy a 20amp breaker and install it in your panel. Should take care of the problem.
