Q:What role does the neutral wire play?

An electrical circuit requires at least two wires, whether it be ac or dc. In mains ac, one of the wires is connected to ground for safety. This is called the neutral. So the circuit will still work without the neutral connected to ground but not be so safe. The reason the neutral makes it safer is that a current will flow in the event of a fault on the hot wire and cause the protection (fuse or breaker) to operate.

Q:I'd like to know what quot;wiremeans when it refers to computers. Is it the computer itself or the Internet?

Need context to answer your question. Can you give us the complete sentence in which the word appears? EDIT: Thanks for the clarification. Over the wire or Across the wire refer to the days when things were done by telegraph, which was a wired way of communication in the days before computers. If an announcer is, say, 70 years old, he might still use the expression, even though it would now mean that he just got the news. And he would have received it by phone or via computer.

Q:The house was built in the 50's. Two wires are coming up from the switch and two wires are coming down from the top of the wall. I do not see a third wire. I attached the wall light wires left wires to left wires and right wires to right wires and light stayed on, when I moved the switch it threw the breaker. So I used may combination and the switch would not make the light work. It appears one wire may be white and one black. Help please!

I think that 'ed' has given you good advice, if you know *nothing* about electrical wiring inside of the average home and about how two-way switching is wired. The two-way switch is designed for two wall switches at different locations from a common light or other electrical appliance to be able to turn the common appliance 'on' or 'off' independently from each other. If you have one of the boxes that a new two-way switch came in, it should show you, with usual wiring installed under the modern U.S. standard electrical code, which colored wires should be attached to which terminal connections at the INDIVIDUAL, separate switches. Ordinarilary the color coding for electrical wiring in the modern residence is 'white' is for the common 'ground'; 'black' is a 'hot - 115/120 volt-to-ground' wire; and the red should be a loop wire to the common appliance. When one of the wall switches is in the 'on' (up) position, and the other wall switch is in the 'off' (down) position, electrical power is furnished to the appliance. Changing the position of either of the wall switches, cuts off the power to the appliance. And changing the position of either ONE of the switches will supply power again. If you've done any wiring before, you should be able to figure it out, but follow what 'ed' suggested if you can, just to be sure.

Q:Domestic wiring from bank to bank.

I wire money all the time at my job. It takes a little while for the bank to process everything, but it is generally less than 2 hours.

Q:where does the expression 'down to the wire', come from?

I found this online: The wire is used in a four-legged footrace-- at least I've only ever heard the word tape used for races involving bipeds. That and ribbon. The wire in question is an actual wire, and it's used in the Sport of Kings, horseracing. A tape or ribbon would be too stretchy to instantaneously trip the shutter on the finishing-line camera when it was crossed. A horse has no problem busting through a single strand of wire.

Q:is there a way to wire an exit sign to a plug for an outlet receptacle?

Fire codes in most places require it to be hardwired in an emergency circuit or to have a battery back up good for four hours.

Q:electrical wire prices

everything does to some degree cos of the oil used in production packaging and transportation, and because wire is used in massive quantities in industry the companys selling it would lose out if they didnt increase there costs immediatly.
