The voltage potential supplying conductor.
Normally the white wire is neutral, and the black is hot. But if the power comes into the ceiling box and the light is controlled by a switch leg the white my very well be hot. If there is only one wire in the switch box that is a switch leg.
It could mean two things. The first thing would be that the tester is not working. Test on a circuit that you know to be energized. The second thing causing a tester not to light is that the circuit under test is de energized. When using these types of testers always test the black to white wire and then black to ground wire. If the tester indicates there is a voltage to ground and not the white then the neutral white wire is open somewhere in the circuit.
No, the black wire is typically used as the hot wire in a standard electrical circuit in North America. The neutral wire is usually white. It is important to always verify the proper wiring colors and configurations, as they can vary by region and application.
Red, white, and black are standard for a three-way switch (you have two switches that control the same fixture). You should also have a ground wire (copper, unsheathed). The black and red are negative, while the white is positive. It works pretty simply. When the switch is up, the black and white are linked, creating a circuit. When it is down, the red and white are linked. If both switches agree (both are red/white or both are black/white), then the circuit is completed and power flows.

The color of the wires in the electrical circuit are green, black, and white.
The correct order for connecting the red, black, and white wires in an electrical circuit is typically red to black to white.

The correct order of connecting the red, white, black, and green wires in a circuit is typically red to black, white to green.
In an electrical circuit, the black wire is typically the hot wire.
In an electrical circuit, both the black and white wires can be considered hot depending on the wiring configuration.
Normally tiger consist of the colors orange,white,or black with black stripes (black one has white stripes). But asian tigers are normally orange and black! :) -wolf-gal10

Gheisis is in the Black City if Pokemon black, or White forest in Pokemon white. In Black he is dressed normally, without the robe or the staff.
