1. Intro to Electricity

2. What IS Electricity?

3. A form of energy resulting from the existence of charged particles

4. How do we harness this ENERGY?

5. Conductor Something that allows electricity to flow Examples; metal
Water
air

6. Insulator something that does NOT let electricity flow Examples Glass
Plastic
Rubber
Porcelain

7. Power Source Something that supplies electricity Examples; Battery
Generator
solar panel

8. Battery
Portable power source that has a positive and negative. The negative has extra electrons. They want to move to the positive side

9. Circuit
path for electricity to flow

10. Load
Something that uses electricity
Example
Toaster
Ipod
Dvd player

11. Short Circuit
unwanted contact of wires or parts in a circuit resulting in damage or malfunction of the circuit
Example: two bare wires touching

12. Voltage, Resistance & Current

13. Voltage (V) The “push” of electricity in a circuit
Measured in VOLTS (V)

14. Resistance (R) The resistance to flow of electricity
Measured in OHMS (Ω)

15. Current (I) The rate of flow of electricity in a circuit
Measured in AMPHERES (A)
