Electricity SPI 0607.12.1 Identify how simple circuits are associated with the transfer of electrical energy when heat, light, sound, and chemical changes are produced.
Electricity is the constant flow of electrons What Is Electricity? Electricity is the constant flow of electrons
Kinds of Electricity Static Examples An electric charge that collects or builds up on the surface of an object Examples Shocking Lightening
Kinds of Electricity Current The flow of electric charges carried through a material such as wire or other conductors Examples Power lines Computers Appliances
Circuits What are they? Circuits are a path along which electricity moves
Simple Circuits Simple Circuits have 3 parts – energy source Wires (conductors) Object it operates (load)
Simple Circuits energy source load conductors
Switches Switches are used to open and close the circuit. A switch allows two pieces of metal to touch and electrons to flow.
Switches
Working Circuits Closed Circuit These circuits have a complete path to follow. There are no openings in the path.
Working Circuits Open Circuit These circuits do not have a complete path to follow. The power cannot pass from the source to the receiver.
Working Circuits Closed Open
Kinds of Circuits Series These circuits have one path for electricity to flow through. *Some Christmas lights *Flashlight
Kinds of Circuits Parallel These circuits have more than one path for electricity to flow through. *Your house *Power lines
Series vs. Parallel Circuits
