Differentiate between a conductor and an insulator with one example each.
Model Answer
A conductor is a material that allows electric current to flow through it easily, due to the presence of free electrons. Example: Copper. An insulator is a material that resists the flow of electric current, as it lacks free electrons. Example: Rubber.
