2. Output Devices Light bulb motor heater buzzer

3. Motors are used in many machines

4. How does electricity work?

5. Power Source 1,5 Volts 1,5 Volt Cell

6. A Basic Electric Circuit 1,5 V cell Wire Switch Light Bulb INPUT OUTPUT CONTROL

7. What happens inside a battery?

8. Magnets: Opposite poles attract

9. Magnets: Like poles repel

10. Millions of negative charges repelling each other Electric Pressure = VOLTAGE ee e e e e e e e e e e e e e e e ee e e e e e e e e e e e e e ee e e e e e e e e e e e e e ee e e e e e e e e e e e e e ee e e e e e e e e e e e e e ee

11. Voltage Current Resistance

12. Voltage, Current and Resistance Voltage CURRENTCURRENT Resistance

13. The language of Electricity Voltage (V) IS measured in Volts (V) Current ( I ) IS measured in Amperes (A) Resistors (R) is measured in Ohms (Ω)

14. In Conclusion Voltage pushes Current through Resistors to make our Machines work

15. Knowing your basics will make you fly like an albatross!
