electricity and magnetism (stopped at 648)
Materials can become electrically charged
Electric charge is a property of matter
electric field
the stretch of the field is greater near the particle and weaker farther away.
electric charge
is a property that allows an object to expert an electric force on another object without touching it.
Static charges are caused by the movement of electrons
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
can produce a temporary static charge.
Charge polarization
Technology uses static electricity
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
is equal to one joule of energy per coulomb of charge
Charge Movement
Lighting
Materials affect charge Movement
Conductors and insulators
conductor
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
Resistance
Resistance is the property of a material that determines how easily a charge can move through it.
ohms
Electrical resistance is measured in units called
ohms.
