Why are the earbud wires for MP3 player coated with plastic?
To insulate the wires
Why is plastic wrapped around the wires?
Electrical wiring is coated with an insulating material to protect people, animals, objects and other circuits from shock and to protect the circuit of which the wire is a part from shorts and surges. Bag ties are coated to protect the user from cuts and punctures.
Why does a car engine have a burning smell?
Because it's hot, it burns gasoline, and there are plastic-coated wires.
How does plastic over metal wires prevent being electrocuted?
Plastic is a bad conductor of electricity. Metals are good conductors of electricity. You get the metal wires coated by plastic. So when you touch the wire, you do not get the electric current. This nature of the plastic protects you from getting electrocuted.
What are electrical wires coated with to stop us getting a shock?
It varies- heavy cables are usually coated in a rubber compound that is sometimes enriched with graphite. Household cabling is usually coated with plastic compounds of various types.
Why do electrical wires covered with rubber?

Why do wires have plastic around them?
The plastic around wires, known as insulation, protects the wire from damage and helps prevent electrical shocks. It also helps to prevent wires from short circuiting when they come into contact with each other or metal surfaces.
