Insulators , conductors, semi-conductors

           Can you find different kinds of conductors, insulators and semi conductors in your kitchen?

conductor is an object or type of material which permits the flow of electric charge.
An example is the frying pan.
Another is spoon and fork
An electrical insulator is a material whose internal electric charges do not flow freely, and therefore does not conduct an electric current under the influence of an electric field
Place mat
Pot holder
Serving spoons
Plates

semiconductor is a material which has electrical conductivity to a degree between that of a metal  and that of an insulator.
An example is a kettle
