What is the conductor and insulator on an appliance cord?

Answer 1

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.

Answer 2

The conductor on an appliance cord is typically made of copper and is responsible for carrying the electric current to power the appliance. The insulator is a material such as rubber or plastic that surrounds the conductor to prevent electric shocks and protect against physical damage.
