yes.. had to find out myself with a multimeter and phone test,, white wire is positive on a Samsung travel adapter.
A table lamp using AC (alternating current) does not have a positive wire, but many will color-code the wires white and black within the circuit. <><><><> As said, no positive and negative, but there IS a hot and a neutral. The hot wire may have ridges running the length of the insulation (or be colored black if separately insulated). The hot wire connects to the brass colored screw, and feeds power to the base of the bulb. Yes, will work if reversed, but is not according to electrical code. White or unridged wire connects to silver colored screw, which connects to the shell of the bulb base.
If you are talking about the wiring of buildings/houses then blue would be a hot with ac current. If you mean wire in electronics then it would also "usually" be a positive but if there is any danger you should never assume. A tester could save you from having to buy a new component or your life.AnswerThe European convention is that blue insulation indicates a neutral conductor, brown, black, or grey insulation indicates a line conductor, and a yellow/green striped conductor indicates an earth conductor.
White wire is usually used as a neutral conductor and a 240v ac unit has no neutral. Each leg of the 240 volts is a "hot" leg However, very often a 12/2 or 14/2 NM cable is used to power small window ac units using 240v. In this case one of the conductors is white, but is not a neutral. It is good practice to mark the white wire with black tape so it is readily identified as a hot wire.
White is neutral in home wiring. Red is sometimes used in 3-way switches and dimmer applications, so it is likely red is hot in your application if it pertains to home wiring. The term positive would just apply to DC wiring since AC goes positive and negative. For example your car battery has Red as Positive and Black as Negative.
Use 8 gauge wire.
Yes, you can cut the end connector of the adapter and peel the 2 wires. The white wire is the positive and the black one is the negative, then open the battery place of the MP3, remove the battery and hook the negative wire to the spring and stick the positive wire to the other end. Adjust your adapter to 1.5V and run your MP3 player :)
In a DC circuit Red is positive and Black is negative. In AC systems White is neutral and Ground is green or green-yellow stripe.
yes it can! but first u must open up the ac adapter, put some blutac in it and put a wire conecting between the metal disk inside the ac adapter and the cell phone!
Black with white stripe = Positive. I tested this with a AC to DC wall plug. ________________________ It really doesn't matter if you connecting the wire yourself. As long as you define one as positive and the other as negative and keep that same definition throughout the system, it will work.
The positive wire on a 1984 Mercedes 380 SL for the AC compressor is the green wire. It provides power to run the compressor when the air conditioner is turned on by the driver.
the AC adapter.... do you mean where to plug the AC adapter in? E-mail me at taylordc@live.ca so i can help you
I don't think it will. If the source is AC, the live wire will alternate as well.
YesCaveatIn general, when working with DC, the red wire is positive and the black wire is negative. In the US and Canada, when working with AC, the colored wires (red, black...) are "hot", the white wire is neutral and the green or bare wire is ground.Note that the above is NOT a requirement for "switch legs".
If it is a power pack that gives jump starts it would be the red, yellow or blue the positive would be white or black. If it is a power pack that gives jump starts it would be the red, yellow or blue the positive would be white or black.
When working with DC (direct current) voltage, IN GENERAL, red is positive and black is negative. But the reality is, a manufacturer may select different colored wires to represent different things, and it is entirely up to the manufacturer to make those decisions.But since this question is under the heading, "Home electricity", you may have asked the wrong question, since home wiring is AC (alternating current), and there is no such thing as a positive or negative wire.
no the psp go has not a regular psp ac adapter
There is no "positive" wire in an Alternating Current (AC) system, which is what a standard AC power cord or flex is used on. In a cord or flex for a small electrical appliance there is a always a "Hot" or "Live wire, a "Neutral" wire and maybe also a "Ground" or "Earth" wire. The "Hot" or "Live" wire is colored * Black in the US, Canada and other countries using a similar 60 Hz household AC power system.* Brown in Europe and other countries using a similar 50 Hz household AC power system. The "Neutral" wire is colored * White in the US, Canada and other countries using a similar 60 Hz household AC power system.* Blue in Europe and other countries using a similar 50 Hz household AC power system. The "Ground" or "Earth" wire is colored * Green in a cord or flex in the US, Canada and other countries using a similar 60 Hz household AC power system.* Green and Yellow in Europe and other countries using a similar 50 Hz household AC power system.
