Circuit Circuit – A complete path along which electrons flow (negative to positive) 3 basic types Series Parallel Series-Parallel Combo

Series Circuit Components (resistors, LED’s, batteries) are connected in a line, one after another. A continuous path for electrons to flow Series Circuits are very common

Series Circuits In a series circuit, if a lamp 'blows' or a component is disconnected, all the components stop working. If you put more lamps into a series circuit, the lamps will be dimmer than before. Uses less wiring than parallel circuits.

Parallel Circuits Are arranged so other parts continue to work even if one part fails. Common in TV’s, Radios, and stereos The different components are connected on different wires.

Parallel Circuits In a parallel circuit, if a lamp 'blows' or a component is disconnected from one parallel wire, the components on different wires keep working. Unlike a series circuit, the lamps stay bright if you add more lamps in parallel.

AC / DC AC: Alternating Current Electrons keep switching directions, sometimes going "forwards" and then going "backwards." Generators Power plants Wall outlets DC: Direct Current Electrons flow steadily in a single direction, or "forward." Batteries Solar cells Fuel cells Some types of generators
