Electricity - Coggle Diagram
Electricity
1.1 Materials can become electrically charged
Electric charge is a property of matter
Electric charge
: A property that allows am object to exert an electric 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 is called.
Charge Polarization
Technology uses static electricity
1.3 Electric current is a flow of charge
1.2 Charges can move from one place to another
Static charges have potential energy
Electric Potential
Electric Potential
: The amount of electrical potential energy per unit charge at a certain position in an electrical field.
Volt
: One volt is equal to one joule of energy per coulomb of charge.
Charge Movement
Electric Potential Energy
Lightning
Materials affect charge movement
Superconductors
Conductors and Insulators
Conductors
: 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.
Grounding
Grounding
:Providing a harmless, low-resistance path---a ground--- for electricity to follow.
