These are things that help us control the flow of electric current.
Conductors allow electricity to flow easily. Example: copper wire
Insulators stop the flow of electric current. Example: the plastic covering on a wire
Resistors slow down the flow of electric current. Example: the filament in a light bulb.

Series circuits - one path, if one light goes out, they all go out, all resistors get the same amount of energy
Parallel circuits - two or more paths, if one light goes out, only that light goes our, each resistor only gets the amount of energy it needs
Both circuits all electrical current to flow.
Both circuits use an energy source, conductors(metal wire), insulators(plastic covering),
resistors (ex: light bulb), and a switch
