Does a 220 volt ac contact get a positive and a negative?
A 220 vac circuit has 2 hot wires and a neutral. The neutral stays at 0 volts and the hot wires vary between positive and negative. When one is positive, the other is negative.
How can you tell which is positive and which is negative on a speaker hookup?
Depending on colours of course black is usually negative and the other colour (generally red but depends) is positive. Get a D-cell Battery. Now get two pieces of speaker wire. hold one wire on the positive terminal of the battery and hold the other on the negative side of the battery. touch the wires to the positive and negative posts on the speaker. if the cone moves out ward the positive and negative are correct if it moves inward then the positive and negative are reversed (out of phase.) this simple test will allow you to see which terminal is which.

Change positive ground to negative old tractor?
---------------- You really don't need to replace anything! But his will allow you to ADD the more common negative ground accessories. This will work for tractors, trucks, cars... whatever. Switch the wires at the coil. Reverse your battery connections (turn your battery around and connect positive cable to positive post on the battery) and connect the negative cable to the ground. Connect a wire from the positive post of the battery. Take the other end of the wire and brush it against the "F" (field) post on the voltage regulator until you see a few sparks. DO NOT CONNECT THIS END, just brush it a couple times. Check all your fuses. Reverse the wires on your gauges or the display will be backwards.
What do negative and positive legs of led mean?
The LED will only emit light when its wires are connected to the battery in the correct direction. When it's flipped, it doesn't shine. The designations of its "legs" ... or wires, or terminals, or leads ... tells you which side of the battery each one must connect to, if you want it to shine.
Is polarity negative or positive?
Yes. Electrons always flow from the negative pole to the positive pole. In a Direct current(DC) circuit, one pole is always negative, the other pole is always positive and the electrons flow in one direction only. In an alternating Current (AC) circuit the two poles alternate between negative and positive and the direction of the electron flow continually reverses. In DC circuits (e.g. for a battery) positive is usually marked red and negative is usually marked black, but other color schemes are very common in automotive and telecommunications systems. In AC systems which are at no point connected to earth (unlike domestic mains wiring where the neutral is commonly earthed at substations and generators) polarity is not important as the two wires alternate polarity many times per second.
How can you tell the difference between positive and negative wires?
usually, positive wires have a blue rubber coating, whereas negative wires have a red rubber coating.
