                     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?
