1. Applications of Static Electricity
electrostatic spray painting
electrostatic
precipitator
electrostatic duster

2. Applications of Static Electricity
Conductor: an object that lets electrons move easily through it
e.g. metal wire

3. Applications of Static Electricity
Conductor: an object that lets electrons move easily through it
e.g. metal wire
Insulator: a material that does not easily allow the movement of electrons through it
e.g. plastic

4. Applications of Static Electricity
Grounding: connecting an object to a large body, like Earth, that is capable of removing any electric charge on the object
grounding

5. Applications of Static Electricity
Grounding: connecting an object to a large body, like Earth, that is capable of removing any electric charge on the object
Negative object: excess electrons flow from the object to the Earth until it is neutral

6. Applications of Static Electricity
Grounding: connecting an object to a large body, like Earth, that is capable of removing any electric charge on the object
Negative object: excess electrons flow from the object to the Earth until it is neutral
Positive object: electrons flow from the Earth to the object until it is neutral

7. Applications of Static Electricity
Electrostatic Spray Painting: positively charge the object and negatively charge the paint particles

8. Applications of Static Electricity
Electrostatic Spray Painting: positively charge the object and negatively charge the paint particles
opposite charges attract

9. Applications of Static Electricity
Electrostatic Spray Painting: positively charge the object and negatively charge the paint particles
opposite charges attract
-paint particles are attracted to the object and less is lost as over spray

10. Applications of Static Electricity
Electrostatic Duster: rubbing the duster across a surface causes the duster to become charged by friction.

11. Applications of Static Electricity
Electrostatic Duster: rubbing the duster across a surface causes the duster to become charged by friction.
charged objects attract neutral objects

12. Applications of Static Electricity
Electrostatic Duster: rubbing the duster across a surface causes the duster to become charged by friction.
charged objects attract neutral objects
-neutral dust particles stick to charged duster

13. Applications of Static Electricity
Electrostatic Precipitator: a device to remove dust particles from the exhaust gas from industry

14. Applications of Static Electricity
Electrostatic Precipitator: a device to remove dust particles from the exhaust gas from industry
1. smoke particles pick up a negative charge

15. Applications of Static Electricity
Electrostatic Precipitator: a device to remove dust particles from the exhaust gas from industry
1. smoke particles pick up a negative charge
2. charged particles are attracted to positive plates
3. clumps of smoke particles collect up on trays and are removed for disposal

16. Applications of Static Electricity
Photocopying: selenium is an insulator but becomes a conductor when exposed to light
