Electronics for Kids; Electrical Insulators and Conductors


Assalamu’alaikum wr wb,

A good ELECTRICAL CONDUCTOR is a substance which allows electricity to flow through it easily. The opposite of a good electrical conductor is a good ELECTRICAL INSULATOR, which stops electricity from flowing through it.

This experiment will show you whether materials are good conductors or not.

1. Making a Circuit Tester

Turn ON the switch, light the bulb by allowing the probes to touch each other.

2. Now touch a copper coin with both probes.

Did you get a light?

Try the same with:

  • a button

  • a piece of paper

  • a screwdriver (the metal bit)

  • a screwdriver handle (plastic)

  • a piece of wood

  • the lead from a pencil

Did you get a light?

When you received a light the material we use is a conductor. However, you should remember that water can change insulators into conductors. In other words if an object is wet it can allow electricity to flow through it. This is one reason why you should never handle electrical equipment (even switches) with wet hands!!

Wassalamu’alaikum wr wb.
