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
