1.1 Materials can become electrically charged - Coggle Diagram
1.1 Materials can become electrically charged
Electric charge is a property of matter
Electric charge is a property that allows an object to extert and electric force on another object without touching
Electric field
Static charges are caused by the movement of electrons
static charge is a buildup of electric charge in an object caused by the presence of many Particles with the same charge
How materials affect static charging
Charging by induction
charge polarization
Technology uses static electricity
1.2 charges can move from one place to another
Static charges have potential energy
Electrical Potential Energy
Electrical Potential
one volt is equal to one joule of energy per coulomb of charge
Charge Movement
Lightning
1) Charge Separation
2)Charge Buildup
3)Static Discharge
Materials can affect charge Movement
Conductors and insulators
Resistance
Superconductors
Grounding
1.3 Electric current is a flow of charge
Electric charge can flow continuously
Current, Voltage, and Resistance
Ohm's Law
Current=voltage/resistance --- I = V/R
Meauring electricity
Electric cells supply electric current
Electrochemical cells
Solar Cells
