Electricity (Static charge (How materials affect Static electricity?…
Electricity
Static charge
Buildup of electric charge in an object caused by the presence of many particles
How materials affect Static electricity?
Contact occurs when one materials electrons are attracted to another
Charged by Contact
When two uncharged objects touch electrons move from one to the other
Charging by induction
Buildup of a charge without direct contact
Charge polarization
Induction can build a charge by changing the position of electrons
Static charges have potential energy
Electric potential enegy
Electric potential
Charge movement
Lightning
Materials Affect charge movement
Conductors and insulators
Resistance
Superconductors
Grounding
electric charge can flow continuously
Current, voltage, and resistance
Ohm's law
Measuring electricity
Electric cells supply electric current
electrochemical cells
Primary cells
Storage cells
solar cells
Electric charge
Property that allow an object to exert an electric force
Technology uses static electricity
