Electricity Presentation for Year 9

1. ELECTRICITY POWER

2. Materials used in electricity Conductors: allow electric current to pass through Insulator: materials which do not allow current to pass through Semiconductors : electrical properties fall between conductors and insulators Electrolyte : liquids that allow electricity/current to pass through them.

3. WHAT IS ELECTRITY Movement of tiny particles called ELECTRONS. It cannot be seen but can be felt. Particles can only move through conductors.

4. ELECTRIC CIRCIUT An electric circuit is a design of how electrons flows from power source and back. Components of an electric circuit ,buzzer, powersource (dry cell), wire. Switch , bulb and cell holder.

5. DRY CELL IMAGE AND SYMBOL Is a source of electricity that produce low electric power. It is used in lab experiments. Dry cell arrangements in a c

6. ELECTRIC COMPONENTS

7. SWITCH When the switch is closed we say the circuit is complete. When the switch is open we say the circuit is incomplete

8. COMPLETE CIRCUIT DESIGN

9. Variable resisistor symbol

10. ASSIGNMENT DESIGN THE CIRCUIT USING SYMBOLS
