Electricity
Electricity is the energy from the flow of electrons.
CONDUCTORS
Conductors are materials that freely allow the flow of electrons with very little resistance.
SEMICONDUCTORS
Semiconductors are materials that do not allow electors to flow freely but do not directly stop them either.
INSULATORS
Insulators are materials that greatly impede or stop the flow of electrons with very high resistance.
Conductor
EXAMPLE OF CONDUCTOR - copper
Semiconductor
EXAMPLE OF SEMICONDUCTOR - silicon (used in computer chips)
Insulator
EXAMPLE OF INSULATOR - rubber
