Conductors and Insulators
A conductor is a material that allows electricity to flow through it.
An insulator is a material that electricity cannot flow through.
To determine whether an object is a conductor or insulator, you could build a simple
circuit with a battery, light bulb, and some wire. However, will use our imagination and EQ
If you touched the free ends of the wire to the object you are testing would the light
bulb light up. If yes the object is a conductor, if it does not, the object is an insulator.
