Electricity

circuit The pathway by which electricity flows Example: Computer

source Where the electricity comes from (power source) Examples: Battery, Outlet Source

load Consumes, or takes in, electricity Examples: Buzzer, Lightbulb, Fan

conductor Allows electricity to flow through it Examples: Most metals

insulator Stops the flow of electricity Examples: Most nonmetals

Complete (Closed) circuit A pathway that lets electricity flow Example: Phone plugged in

Incomplete (open) circuit A pathway that does not let electricity flow Example: Doorbell not in use

Series circuit A circuit where electricity flows along a single pathway Example: Christmas lights

parallel circuit A circuit where electricity flows along multiple pathways Example: Appliances
