The active or hot wire in an electrical circuit is the wire that carries the current from the source to the load. It is typically colored black, red, or another color distinct from neutral and ground wires. The active wire is where the electrical energy is supplied to power devices or appliances.
In most installations in a two wire circuit the colour will be black. In a three wire circuit there will be two ungrounded conductors using a colour code of black and red.
The wire that goes in the "COM" terminal is usually the black wire, which is the common wire. This wire is used as the reference point for the circuit.
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 voltage potential supplying conductor.
In a household circuit, with a "hot" conductor insulated black and a white neutral, the black wire should connect to the center terminal of the socket. The outside part of the socket usually has a brass screw (for the black wire) and a nickel screw (for the white wire).
In an electrical circuit, the black wire is typically the hot wire.
In an electrical circuit, the black wire is typically the hot wire.
In an electrical circuit, the black wire is typically designated as the hot wire.
In an electrical circuit, the black wire is typically considered to be the hot wire.
In an electrical circuit, the black wire is typically considered hot.
In an electrical circuit, the black wire is typically considered hot.
In an electrical circuit, the red wire is typically considered the hot wire, while the black wire is usually the neutral wire.
In an electrical circuit, the black wire is typically the hot wire, while the white wire is the neutral wire. Both wires can carry electricity, but the black wire is the one that carries the current to the device, while the white wire completes the circuit by returning the current to the source.
That depends if it is automotive or household wiring. On a car a black wire is almost always ground. On house wiring black is the supply (hot) wire.That depends if it is automotive or household wiring. On a car a black wire is almost always ground. On house wiring black is the supply (hot) wire.
The black wire is not really needed in a circuit because it has a negative voltage
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.
