How do you determine the white and black wire if they are not marked?

If you are talking about lamp cord that table lamps use, look for a raised rib on one of the parallel wires. This is the identified wire so it will be connected to the neutral (silver) blade of the plug.

Be careful - electricity is dangerous.
In the above answer, third sentence both wires will read to ground as the hot wire will read to ground through the load.
The hot wire is the live supply, the load is the wire going to the appliance, so I assume you are talking about wires at a switch, if so, it doesn't matter; when they are closed (touching) the light will be on, when they are open (not touching) the light will be off. DANGER don't touch any potentially live wires until the circuit has been isolated and proven to be dead.

∙ 13y agoThe wires have a coating that surrounds the conductor and it is called insulation. This insulation comes in different colours. These colours represent different uses of the wire. White represents the neutral wire and green represents the ground wire. Blue and yellow are used in control DC circuits. All other colours can be used as "hot" wires.

What to do with the white wire in track light with black green and white wires if the house does not have a white one?
The white is neutral. The house does have a neutral wire even though it may be black. One of those black wires is the neutral and the other is the hot wire. You will have to determine which is hot and which is neutral. You can easily do this with a voltage tester. The wire that lights the tester is the hot. When you wire the light simply wire the hot to hot, and the white and green to the other wire.
White wire a black wire a red wire and a bare wire?
white wire = neutral bare wire = ground black wire = line voltage red wire = returned from a switch, or the other phase of line voltage in order to supply 240VAC

How do you connect timer white and black house wire with red black and white wires?
House wire is "line" Black & White house goes to Black & White of Timer; the "load" (e.g. Pond Pump, etc.) is connected to the Red & White. Specifically, put all 3 whites together (nut or terminal); House (source)(line) Black to Timer Black; and "load" Black to Timer Red. The Red wire is the "Timed" (switched) hot wire.

Is Black wire vs black wire with white stripe positive or negative?
Any marking (a white stripe, bump molded into the cable, different wire colours) is an indication for your reference only. It doesn't matter, as long as you connect the marked side on the amplifier to the same polarity on the speaker side.
How do you wire the last fixture in a parallel circuit?
The last fixture in a parallel circuit is wired the same as the first. In North America, all of the fixtures are wired black wire to black wire and white wire to white wire. The black wire being the "hot" wire and the white wire being the neutral wire.
When wiring up a photocell where do the leads get connected?
Black Wire from photocel to hot wire(black) coming in red wire to light fixtures black wire. White wire to neutral wires all light and power source white.
What is the lamp black wire with white stripe?
If you are asking about the electrical cord on a lamp, the black wire with the white stripe is the neutral conductor.
If both wires for a ceiling light fixture are black how do you tell which is the live wire and which is neutral?
If both wires are black, the one that connects to your white wire is the one that should have little writing on it. Black to the plain black wire, white to the wire with writing.

Which wire is black and which wire is red when they are not marked?
Color coding is different for different pieces of equipment. More information is needed.
When installing a Y shaped electric range plug and it has places for three wires and you have a black wire white wire and a bare copper wire so which wire goes where?
Usually the bottom leg is the ground. It should be marked as such with a g or the universal ground symbol, which is stacked dashes that get smaller from top to bottom. In this instance the white and black are both power legs and go to the two angled legs. Use your meter to verify this.
