Electrical Circuit A complete path around which electrical current flows
Electric Current The movement of electricity (electrons) through a wire
Electron A tiny particle with a negative charge
Switch A device used to open or close a circuit, controlling the flow of electricity
Conductor A material that allows electricity to pass through it easily (e.g., copper, silver, iron, or a metal paperclip)
Insulator A material that does NOT allow electricity to flow through it (e.g., plastic, rubber, glass, wood, or yarn)
Circuit Type Closed Circuit Description A complete path with no gaps or breaks. Will the Bulb Light? Yes
Circuit Type Open Circuit Description A path with a gap, break, or open switch. Will the Bulb Light? No
Feature Pathways Series Circuit Only one path for the current. Parallel Circuit Two or more separate paths.
Feature Adding Bulbs Series Circuit Bulbs will become dimmer as you add more. Parallel Circuit Bulbs stay the same brightness.
Feature Removing a Bulb Series Circuit If one bulb is removed, all go out. Parallel Circuit If one is removed, the others stay on.
Feature Common Use Series Circuit Holiday lights (sometimes). Parallel Circuit Household wiring.
Insulation Wires are covered in plastic or rubber because they are excellent insulators, which keeps electricity from leaving the path and makes them safe to touch
Failure Points A circuit might fail if the battery is dead, there is a break in the wire, or if both wires are connected to only one pole of the battery
Conductor Materials Metals like copper and silver are excellent conductors. Materials like wood, yarn, and glass are not
