Electricity - Coggle Diagram
Electricity
1.1 Materials can become electrically charged
Electric Charge is a property of matter
Electric Charge
A property that follows 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 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
Built up with charge without direct contact
Charge Polarization
Technology uses static electricity
1.2 Charges can move from one place to another
Static Charges have potential energy
Electric Potential Energy
Electric Potential
Electric Potential
Is the amount of electric Potential energy per unit charge at a certain position in an electric Field.
Volt
A potential of one volt is equal to one joule of energy per coulomb of charge.
Charge Movement
Lightning
Charge Separation
Charge Buildup
Static Discharge
Materials Affect Charge Movement
Conductors and Insulators
Conductor
A conductor is 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
Is the property of a material that determines how easily a charge can move through.
Ohms
Electrical resistance is measured in units called ohms
Superconductors
Grounding
Grounding
Grounding means providing a harmless, low-resistance path-a ground-for electricity to follow.
Electric Current Is a flow of charge
Electric Charge can flow continuously
Electric Current
Electric current is the form of electricity used to supply energy in homes, schools, and other buildings
Current, Voltage, and Resistance
Ampere
An amp is the amount of charge that flows past a given point per unit of time
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
Primary Cells
Storage Cells
Solar Cells
