Sage Project
Series Circuits
•       The electrical components connected in
line or in a single path.
–        If 1 component dies or breaks there will be
no flow of electricity and nothing will work.
•     Old style Christmas lights (If 1 burned out none
would work)
Parallel Circuits
•       The electrical components are
connected across parallel paths allowing
the electrical energy to flow evenly
across multiple paths.
–        If 1 component dies or breaks the electricity
will still flow across the other legs and all
other components will still work.
•     New style Christmas lights (If 1 burned out the
rest still work)
Series-Parallel circuit
•   A series parallel circuit combines both a
parallel circuit and a series circuit by either
having a series circuit before, or after the
parallel component, as on or more leg of the
parallel circuit or a combination of these.
•   If a portion of the series component goes down
nothing that follows that portion will work as
the circuit has been broken, however if the
parallel components still have energy
Voltage Loss & Flow of Energy
•    Voltage loss
– Lights in series
– Lights in Parallel
•    Flow of Energy
– What would happen if the switch was
parallel to the rest of the circuit?
– What would happen if the switch was in
series with the circuit?
