Materials for the school fundraiser will come home today. This is how we pay for any
class field trip we take. Please help us out in any way you can.

Conductors, Insulators and Resistors

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.

Electrical Circuits

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
