why electric wire coated with PVC ?

PVC is short form of Poly vinyl Chloride. It is a polymer which is an insulator which means it does not allow electricity to pass through it. It is wrapped around electric wires so that two wires can be crossed around one another like in many cases you must have seen in your houses where two or more wires runs together.

Also, by any chance a person touches the wire while the switch on, he will not get electric shock as PVC acts as a barrier.

electric Wires are covered with a 
Non-Conducting material in other words an insulator to prevent Risk of an electric Shock...to the rescue,Polyvinylcloride or PVC is perhaps the most common insulating material.

Electrical wires are coated in plastic to prevent conduction of electricity to people or other metallic and conductive materials. Plastic is also flexible and will bend around tight corners and through narrow spaces.
