Electricity and Magnetism
Electricity
Materials can become electrically charged
Electric charge is a property of matter
Electric Charge
=
Property that allows an object to exert an electric force on another object without touching it
Electric field
=
Space around a particle through witch and electric charge can exert this force
Static charges are caused by the movement of electrons
Static charge
=
A build up of electric charge in an object caused by the presence of many particles with the same charge
Charging by contact
How materials affect static charging
Charging by induction
Induction
=
The build up of charge without direct contact
Charge Polarization
Technology uses static electricity
Charges can move from one place to another
Static charges have potential energy
Electric potential energy
Electric potential
Electric potential
=
The amount of electric potential energy per unit charge at a certain position in an electrical field
volt
=
equal to one Joule of energy per coulomb
Charge movement
Lightning
Charge separation
Charge buildup
Static discharge
Materials affect charge movement
Conductors and insulators
Conductor
=
A material that allows an electric charge to pass through it easily
Insulator
=
A material that does not easily allow a charge to pass through it
Resistance
Resistance
=
The property of a material that determines how easily a charge can move through it
ohms
=
The units electrical resistance is measured in
Super conductors
Grounding
Grounding
=
Providing a harmless, low-resistance path - a ground - for electricity to follow
Electric current is a flow of charge
