You have learnt earlier about Conductors. The term Insulator is also very easy to understand and learn. Those substances through which electric charges cannot flow, are called Insulators.


Or you can also say that ” Those substances through which electricity cannot flow are called insulators.  ” Insulators do not allow electric charges to flow through them. So, the electric charges remain bound to them and do not move away (do not move from one point to other point).


Examples of Insulators

Glass, ebonite, rubber, most of plastics, cotton, dry wood, papers, mica, porcelain, dry air, and bakelite are all the examples of insulators because they all don’t allow t0 move electric charges through them.
