1. Current Electricity

2. Understanding A Light Bulb
Filament: thin, tightly coiled wire that heats up to be white hot and emit light
Ceramic bead: insulator that does not allow electricity to travel through (not present in all bulbs)
Wire: wire that is welded to the side of the bulb
Wire: wire that travels down the insulated part of the bulb to the tip

3. How do electrons flow through a light bulb?

4. Complete circuit

5. Incomplete Circuit

6. Factors needed for a current to flow:
Power Source
Circuit
Conductor

7. Understanding Current Electricity
Everything is made up of atoms.
Atoms contain:
Protons (+)
Neutrons
Electrons (-)
Electrical energy is produced when electrons move from one atom to another

8. Why can’t the large amount of electrical energy released by lightning be used to power our TV’s and lights?

9. STATIC ELECTRICITY ELECTRIC CURRENT B. Electrons move along a path
C. Electrons jump
A. Involves moving electrons
D. Measured in AMPS
F. Produced by rubbing
H. Charges build up
E. Continuous flow
G. Can produce a large amount of energy
I. Complete circuit

10. Factors needed for a current to flow:
Power Source
Circuit
Conductor
