The 3 wires are live, neutral and earth. The current travels along the live and neutral because 2 wires are needed for the the current to flow, while the earth is a separate safety wire that normally carries no current, until a fault occurs.

Why you use three pin plug insted of two pin?
In an electrical socket, there are three holes. One is a hot wire, one is a neutral wire, and one is a ground wire. Usually, the hot wire is black. The neutral wire is white. And the ground wire is green. Motors usually have three pin plugs. Other items also have them. When a motor has a three pin plug, the body of the motor is attached to the ground. If a spark goes from the electrical wires to the body of the motor, it will go harmlessly to the ground and not hurt anyone. On a two pin plug, usually one pin is larger than the other. The larger pin goes to the neutral or white wire. It is also grounded. That way if there is an electrical short in the device, it should not electrocute the person using it.
Why you use neutral pin in three pin plug?
In North America the neutral pin is used to complete the circuit. One pin is "hot", one pin is neutral and the last pin is ground.
What is the blue wire for in a three pin plug?
In the UK Brown is the live, blue is the neutral and green/yellow is the earth. The live and neutral are the two wires that normally carry the current.
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.
Why Distance between neutral and groun pin in plug is not same?
No U.
How do you connect the 3 pin plug?
One pin for phase other pin for neutral and third one is for earth/ground wire. In India the right pin is for phase, left pin is for neutral and pin on top side is for ground wire. This third top side pin is slightly bigger and longer compared to phase and neutral pins.
When use a 3-pin mains plug what is the biggest pin for?
On a UK three pin plug the two smaller prongs are Live (brown) and Neutral (blue). The Larger pin is for the Earth wire. This can prevent you getting an electric shock

Which wire is not present in a 2 pin plug?
The earth wire.
What is the purpose of a wire?
it is the brown wire in a three pin plug
Color code in 3 pin electric plug in India?
Green with Yellow Stripe Wire - Earth Wire (E) Blue Wire - Neutral Wire (N) Brown Wire - Live Wire (L) When you look at the plug with the terminals facing towards you: /\ / \ / E \ / \ / \ / L N \ ------------------

No U.
Can you plug a 2 prong plug with the same size slots into a 2 prong plug with one slot larger?
Yes, the larger slot is a polarity slot that is supposed to connect the plug in device to the neutral wire. If the device is a lamp it would make the shell of the lamp the neutral wire connection and the center pin the "hot". If the two wire plug has a moulded plug on it, look for a tracer on the devices power cord. It will be a raised rib or a white tracer on the conductor that is the neutral. Position the two blade plug into the receptacle with the identified conductor into the larger slot, this will give you the proper polarity configuration that the manufacturer recommends. New plugs (caps) today all have a ground pin connected to them and can only connect to the receptacle in one position.
What is the purpose of a live wire?
it gives you an electric shock
