2) Electrical Insulators do not allow electric current to flow through easily: Rubber, Plastic, Fabric, wood, etc.

3) ELECTRIC CURRENT FLOWS ...

4) Electrical conductivity of a material .....

5) Open circuit ...Closed circuit ... gap ....series....PARALLEL   (Better know how to SPELL !)

6) Electricity can cause electric shocks, fires and burns (when appliances are overheated due to high currents flowing through them).

7) CONNECT

8) Negative end, positive end
