Applications of Static Electricity

electrostatic spray painting

electrostaticprecipitator

electrostatic duster

Applications of Static Electricity

Conductor: an object that lets electrons move easily through it

e.g. metal wire

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

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

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

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 neutralPositive object: electrons flow from the

Earth to the object until it is neutral

Applications of Static Electricity

Electrostatic Spray Painting: positively charge the object and negatively charge the paint particles

Applications of Static Electricity

Electrostatic Spray Painting: positively charge the object and negatively charge the paint particles

opposite charges attract

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

Applications of Static Electricity

Electrostatic Duster: rubbing the duster across a surface causes the duster to become charged by friction.

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

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

Applications of Static Electricity

Electrostatic Precipitator: a device to remove dust particles from the exhaust gas from industry

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

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 charge2. charged particles are attracted to positive plates3. clumps of smoke particles collect up on

trays and are removed for disposal

Applications of Static Electricity

Photocopying: selenium is an insulator but becomes a conductor when exposed to light
