In some countries the answer will depend on whether by "plug" you mean "the plug on a flexible cable going to an appliance" or the "socket-outlet" into which a plug can be plugged!
Answer for socket outlets and non-socket outlets for fixed appliances:
In USA, Canada and other countries using a similar 120 volt 60 Hz system, the Hot wire could be either Blackor Red. (The Neutral is White and the Ground is Green or bare wire.)
In USA, Canada and other countries using a similar 240 volt 60 Hz system, there are 2 Hots, one colored Blackand the other colored Red. (The Neutral is White and the Ground is Green or bare wire.)
In Europe and other countries using a similar 230 volt 50 Hz system, the Live wire is Brown. (The Neutral is Blue and the Earth is Green & Yellow.)
Note: for the UK and The Republic of Ireland: please see the Discussion page.
WARNING: It is never ever safe to assume that the color of any wire means that it cannot be "hot" or live".
Do not assume you know which wire is which until you have actually tested it with a proper electrician's test meter or other approved electrical voltage testing device!

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What is the function of the live wire in a 3 pin plug?
A 'live' or 'hot' wire is a wire that is connected to a power source. This wire supplies voltage to a load ( light bulb, hair dryer, etc.). When the load is also connected a neutral or another live wire this becomes a path for the flow of current (amps) known as a circuit.
What are the names of the three wires in a plug?
The three wires in a plug are typically called live, neutral, and earth wires. The live wire carries the current to the appliance, the neutral wire completes the circuit and carries the current back, and the earth wire is a safety feature to prevent electric shocks.
What is the brown wire in a plug?
This is not true in all plugs it all depends on the manufacturer and the product. Plug wires come in all different colors such as red, black, brown, yellow, blue, and so on. So as I said the wire being brown is indicative of a certain manufacturer or product.
What is the color of live wire neutral wire and ground wire in Bangladesh.?

Which wire is not present in a 2 pin plug?
In a 2-pin plug, the wire that is not present is the grounding wire. This type of plug only has two prongs for the live and neutral wires, unlike a 3-pin plug that includes a grounding wire for added safety.
Is the blue wire the live wire?
When ever there is a potential difference between it and ground.
What colour is earth in a plug?
The color of the Earth wire in a plug is typically green or green and yellow stripes.
What is the purpose of a live wire?
