Introduction to Electrostatics

Charging by __________ is when two __________ rub together to transfer electrons

• induction... conductors

• induction... insulators

• friction... conductors

• friction... insulators

Charging by __________ is when a charged object causes a nearby object to be charged on it's surface.

• induction

• friction

• Ka-blongers

things get charged because of the movement of....

• protons

• neutrons

• electrons

• electrons and protons

Protons and elctrons are both charged but ONLY electrons move when things become charged. Why are electrons easier to transfer than protons?

• They are heavier

• They are lighter

• they are in the nucleus of the atom

• they are on the outer shell of the atom far from the pull of the nucleus

When two things rub together electrons transfer from one object to the next- what charge is the object that LOSES electrons?

• negative

• positive

• neutral

When two things rub together electrons transfer from one object to the next- what charge is the object that GAINS electrons?

• negative

• positive

• neutral

When a spark happens this is the movement of _________ to n_________ the charge

• electrons.... neutralise

• protons..... neutralise

• electrons..... normalise

• proton.... normalise

Uses of electrostatics: an electrostatic precipitaror:

• is in a printer to help attract the ink to the page

• is a way to attract the crop spray or insecticide to the crops (plants)

• is a way of removing particles from the air to make it cleaner

• is the way they charge paint to ensure you get an even covering on all sides of the object
