FAQ

I have 1971 slide in truck camper with 5 way pin wiring wires are red, white ,yellow, black,green.need to know what wire's do what...thanks
On a 4 wire harness, normally the left turn signal is green, right is yellow, tail lights are brown, and ground is black. The fifth wire is usually for surge brakes as on a heavy trailer. Take a look at the link below for various configurations.
Why does a thin wire melt and a thick wire glow when put up to the terminals? Explain in terms of resistance and current. Thanks=]
Everything has a temperature at which it will melt. Every conductor also has a resistance, which is just like it sounds, a wire sort of resists the electricity passing through it by heating itself up. If a wire's resistance causes it to heat up so much that it melts, either the wire is too thin, or there is too much current passing through it, or both. A thicker wire can handle the same current without heating up so much that it melts. Sorry I don't have any formulas for you, but I think you should understand it now.
Quick question with hopefully an easy answer. I had a dimmer switch go bad on a light in a dining room. I bought a new switch and put it in. It was working fine, so I thought, then I noticed that when the dining room light is off, the dimmer works on everything else on the circuit, for example outside lights, hall lights, etc. I can dim all of those things when this switch certainly didn't do that before. Also, if the dining room light is on, all of the other things on the circuit I mentioned before do not work at all. I've obviously incorrectly wired the switch somehow, any thoughts on what I did incorrectly and how to fix?
Your switches are wired so that they can both control the light. That is: you can turn it ON with switch 1 and turn off with switch 2, and vice-versa. These are called two-way switches. They have three wires connected to each switch to enable this clever stuff to happen. Your dimmer switch has two terminals because it is a conventional one-way switch and intended to be used all on its own. It not possible to convert the conventional dimmer switch into a two-way switch and it would be almost impossible for you to convert the circuit to use a 2-way switch in conjunction with the dimmer. You won't be able to buy a two-way dimmer for domestic use. Sorry, but you want to do is impossible without some very specialised knowledge and expensive kit, It's not practical for domestic circumstances. The best thing you can try is to get an adaptor to plug into the light socket which will act as a dimmer. The bulb plugs into the bottom of the adaptor. The pair of two-way switches will operate as normal and the adaptor device will do the dimming for you. These things usually have a remote control to work the dimming circuit. Cost about ?15-?29. Try the better electrical shops such as Maplin or John Lewis. EDIT. They are not three-way switches like TJ suggests. These are different things entirely. You would have three of them and even more wires behind them. The dimmer switch does not operate by reducing voltage like another person suggests. They are not simple variable resistors. Dimmer switches contain special circuits which modify the alternating current waveform. This is one reason why they cannot be used with energy-saver bulbs or transformer-fed low voltage bulbs.
i have a 97 chevy blazer. My fuel pump went so i purchased a new one. i did not know that the company changed the wiring on the fuel pump..all the wires are 2gether in the wiring harness and all i have to do is cut off the old harnss and wire the new one in its place. Im not sure exactly how to wire it. What do I do? do i just strip wires and twist them or what?
trace down old wires from pump / sending unit there will be one wire that goes to both the pump and sending unit....... that is ground ....mark old wires before cutting ....... then hook to same on new pump
putting new plug on wire. which wire connectswhere?
If the cord has three wires, black to the brass screw, white to the silver screw, and green to the green screw. If the cord has just black and white, ditto, except use a two-prong replacement plug, no green. If the cord is flat - no colors, just two wires side-by-side - the smooth side to the brass screw, the ribbed side to the silver screw.
I noticed when looking at the wiring sticking out of the end of one of my laptop power cables (the end that enters the battery), that of the green, grey and pink cables there, the green one had snapped. However, my laptop power still works fine, so what does that green wire do exactly?? Is it dangerous to use it even with that wire snapped?
Power requires two wires, but a third wire called a ground wire is sometimes added. Usually the plug that goes into the wall has two or three prongs. If it has two prongs, no ground wire added. If it has three prongs, the ground wire is added. The ground is usually used when metal frames or cases are used. The purpose is to ground or short out the live (hot) wire should it accidentally come into contact with the metal frame, causing the circuit breaker to trip. If the ground wire was not there, it would allow a person to get shocked should they touch the metal frame.
Is there a Martial Arts / Fighting style that uses wires or whats the practices that uses wires called?
wire fu? that's what they do in hollywood. If you mean martial arts with ropes/chains/whips there are several minor styles involving them in wushu. Don't remember the name though.
Two wires, 2.44 m apart, both carry current 2.2 A toward the bottom of the screen. The right wire is extremely long, and the left wire is 0.36 m long. What is the magnetic force on the left wire?
Magnetic force, F = BIL --------(1) where B is the magnetic flux density of the magnetic field caused by the right wire, acting perpendicularly to the left wire in Tesla I is the current in the left wire in Amperes L is the length of the left wire in metres To find B (due to the right wire), you have to use the formula B = (?0)(I)/(2πr) -----(2) where the I in this case is the current in the right wire, r is the distance between the two wires, and ?0 is the permeability of free space, numerically defined as ?0 = 4π×10?7 using eqn (2) so B (due to right wire) = (?0x2.2)/(2πx2.44) = 1.8x10^-7 T using eqn (1) and the value of B calculated above F = (1.8x10^-7 x 2.2 x 0.36) = 1.43x10-7 N
