In residential wiring, if it is used as a switch leg or in 3 wire 240 volt circuits.
the black wire is the hot wire
Red is hot Green is ground White is neutral
In the US, if you only have a black wire (ungrounded or hot conductor) and a white wire (normally a grounded conductor or neutral) there is not a ground wire. Sometimes the white wire is used as a hot, so each wire would have to be identified. <<<< Electrical work should only be done by a qualified electrician.>>>>
If this is a home wiring question and the wires are black and white then black is Hot and white is Neutral. If you also have a red wire, it is the other hot wire, and either the black or the red wire to the white one would be 120 volts, and red to black would be 240 volts.
If you are referring to lamp cord type wire where both wires are brown then yes, connect the wire with the groves to the white neutral and the smooth wire to the black hot wire.
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.
normally the blue and red wires are hot white is standaed for nutral,

White is typically neutral and black is hot. If you are talking about the bare wire, that is ground.
No, there are different occasions when the red of a three wire cable gets used as a hot wire. There also times when the white wire gets used as a hot but has to be re identified as a hot with marking tape. When wiring baseboard heaters the cable used is red and black with no white wire in the set.

You have a 3 way switch. Your black wire is the hot wire. Your green wire is the ground wire. Your red and white wires go to the light and other switch. You should have gotten a wiring diagram with your switch.

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.
a shorted out outlet can cause a backfeed on the white wire, an open circuit on the white wire with and electrical appliance plugged in to an outlet can cause the same type of backfeed
