Applications of Static Electricity electrostatic spray painting electrostatic precipitator 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 neutral Positive 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 charge 2. charged particles are attracted to positive plates 3. 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
