Because there is a potential difference between the live and neutral wires.
The neutral is supposed to be grounded on all installations, single phase and three phase, according to the electrical code so no you will not get a shock if you touch the neutral wire. If the neutral wire is not grounded you might in some circumstances get a little tickle of voltage.
when high voltage electricity is live
Because it conducts electricity only when it is connected to a "live' wire.
Double insulation is a safety feature in electrical appliances where an extra layer of insulation is provided between the conductive parts and the exterior surface. This prevents direct contact between the user and any conductive parts that may become live due to a fault. If a fault occurs and the live parts touch the conductive parts, the double insulation ensures that the user is protected from electric shock by preventing the flow of electricity to the exterior surface of the appliance.
It definitely will NOT protect you because the ELR will not trip for a current going up the live and coming back down the neutral.
Yes but only if you are in contact with the hull of the hull of the aeroplane. i.e. earthed.

Living things get a shock when an electric current flows through it. When the bird sits on a live wire, the circuit is incomplete and there no potential difference is set up across it's body. Now, if the bird happens to touch the neutral wire and live wise simultaneously, for example while trying to fly between the power lines, then sure it will get a shock and will be dead.
· Never touch the live electrical wires · Never touch electrical plugs with wet hands · Use dry or rubber soled Sholes while repairing the electrical works · Never touch the live and naked wires

The actual resistance heating element is inside the burner (which is actually a hollow tube), and is insulated from it. The part you can see and touch is not electrically connected and is not live.

The live wire is brown in coulor while the earth wireis green and yellow in color and neutral wire is blue in colour. Uses of these three wire: Live wire:It's connected with fuse.It carries a voltage which drives electric current through the electrical appliances. Earth wire:It is a safety device and protect us from electric shock. Neutral wire:It offers a return path by electric current.
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
it gives you an electric shock
Because it conducts electricity only when it is connected to a "live' wire.
IF Neutral is connected to the Switch then Live still exists on the socket even if the Switch is OFF.In such a situation a person can get a shock as Live can form a circuit thru the body to Ground.
