Electricity and Magnetism
Electricity
Materials can become electrically charged
Electric charge is a property of matter
Electric charge is a property that allows an object to exert an electric force on another object without touching it.
Electric field is the space around a particle through which an electric charge can exert this force
Static Charges are caused by the movement of electrons
A static charges is 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 is the buildup of a charge without direct contact.
Charge Polarization
Technology uses static electicity
Charges can move from one place to another
Lightning
Charge movement
Electric Potential
Volt is equal to one joule of energy per coulomb of charge
Electric potential is the amount of electric Potential energy per unit charge at a certain position in an electric field
Electric Potential Energy
Materials affect charge movement
Conductors and Insulators
Conductors is a material that allows an electric charge to pass through it easily
Insulator is 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 it
ohms is electrical resistance and its unit is ohms
Superconductors
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 is another name for a flow of charge
Current, Voltage, and resistance
ampere is the standard unit of measure for current
Ohm's Law
Ohm's law is expressed in the formula Current= Voltage/Resistance
Measuring Electricity
Electric cells supply electric current
The other type is the electric cells, which produces electric current using the chemical or physical properties of different materials
Electrochemical Cells
Solar cells
Circuits and Electronics
Charge needs a continuous path to flow
Electric charge flows in a loop
Circuits is a closed path through which a continuous charge can flow
Circuits make electric current useful
Electronic technology is based on circuits
