Electricity
Materials can become electrically charged
Electric charge is a property of matter
Electric charge
A property that allows an object to exert force on another object without touching it
Electric field
The space around a particle through which an electric charge can exert this force
Static charges are caused by the movement of electrons
Static charge
A buildup 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 buildup of a charge without direct contact
Can produce a temporary static charge
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 electric field
Volt
Another term for electric potential (The units that electrical potential is measured in)
Charge movement
Lightning
Charge separation
Charge buildup
Static discharge
Materials affect charge movement
Conductors and Insulator
Conductor
A material that allows an electric charge to pass through it easily
Insulator
A material that does not easy 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 that electrical resistance is measured in
Symbol is omega
Superconductors
Grounding
Grouding
Providing a harmless, low-resistance path for electricity to follow
Electric current is a flow of charge
Electric charge can flow continously
Electric current
Another name for a flow of charge
Current, Voltage, and Resistance
Ampere
The standard unit of measure for current
Ohm's Law
Ohm's Law
Current = Voltage/Resistance
I = V/R
Measuring electricity
Electric cells supply electric current
Electric cell
Produces electric current using the chemical or physical properties of different materials
Electrochemical cells
Solar cells
