Switches and Lamps in Series Circuits.
An open switch in a
series circuit will turn everything off,
because the circuit will be disconnected from the cell.
When lamps are connected in
series,
the more lamps in the circuit the
dimmer they get,
because the voltage is divided between them.
If one
lamp in a series circuit
breaks or fails,
all the others will go out
with it.
For this reason, lamps are
always connected in parallel
(except Christmas Tree Lights or Fairy
Lights,
where the large mains voltage is conveniently divided between the
lamps).
