There are two conductors in an appliance cord, separated from each other. Each one is a
long, thin 'wire' of copper or aluminum, connected at one end to the appliance, and at the
other end to one of the prongs on the plug that plugs into the wall outlet.
Each conductor is completely enclosed over its entire length in a continuous insulating jacket
of plastic, rubber, or cloth, and the two of them are physically combined into a single jacket.
If you ever see any of the conductor through a hole in the jacket, then the cord is worn and
should be replaced with a new one.
On the power cord of an electrical appliance, the only conductor you can see is the two (or three) little prongs on the very end of the cord, that get plugged into the wall. Everything else you can see is insulating material. (If it ever becomes possible to see any conductor anywhere else in the cord, then the cord is damaged and dangerous, and must be replaced.)

conductor!!!!! ;))
yes
The metal is the conductors, the rubbery or plastic stuff is the insulator.
