Electrical Energy
Unit Essential Question(s):
How does energy move through a complete circuit?
LeQ: What makes a circuit complete?
Conductor- a substance, body, or device that readily conducts heat, electricity, sound, etc
Insulator- a material of such low conductivity that the flow of current through it is negligible.
Complete Circuit- Electrons flow from the source to the load and then back to the source.
Electrical Source- supplies energy to the circuit
Wires- a slender, stringlike piece or filament of relatively rigid or flexible metal, usually circular in section
,manufactured in a great variety of diameters and metals depending on its application.
Switch- The function of a switch is to start or stop the flow of charges.
Electrical Device- appliances (light bulb, microwave, cell phone, etc.) that use electrical energy
Metal Base- electric charge flows out and back to the battery (bottom of bulb)
Filament- changes electric energy to heat and light (squiggly lines inside light bulb)
Support Wires- hold filament in center of light bulb
Metal Thread- Conductor that lets energy in as well as screw light bulb into a socket

leq: How are series and parallel circuits different?
Series Circuit- A complete circuit where all the electrical devices are in one "loop", causing each device to share the energy
Parallel Circuit- A complete circuit where each electrical device has its own "loop"; each device does not have to share the energy
Parallel Circuit- A complete circuit where each electrical device has its own "loop"; each device does not have to share the energy
leQ: How do electrical charges react with one another?
Neutral- same number of positive (+) and negative (-) charges so it does not go either way
Attract- when opposite charges pull each other together (+ and -)
Repel- when two of the same charge push each other away (+ and +, OR - and -)

Repel- when two of the same charge push each other away (+ and +, OR - and -)
LEQ: HOw is energy flow different between a series and parallel circuit?
View the power point above to see Chucky the Charge explain how charges deliver energy through a series and parallel circuit.
