Slides 6-15 ANSWERS
• Identify if the light bulb(s) will be
• 1. the same brightness or
• 2. one bulb will be brighter than the other.
• Explain how you know.
CIRCUIT A WOULD HAVE BRIGHTER
BULBS. In a series circuit, when you
add bulbs the energy is shared with
each bulb so the more bulbs you add,
the dimmer the light gets.
CIRCUIT A WOULD HAVE BRIGHTER BULBS. In the series
circuit B, when you add bulbs the energy is shared with
each bulb so the more bulbs you add, the dimmer the
light gets. In the parallel circuit A, each bulb has their
own path to the battery so they do not share the
voltage.
CIRCUIT B WOULD
HAVE BRIGHTER BULBS.
In a series circuit, when
you add batteries the
voltages add together
because there is only
one path. Since there
are more batteries in
circuit B, there is more
energy going to the
light bulb.
CIRCUIT B WOULD HAVE
BRIGHTER BULBS. In the
series circuit A, when you
add bulbs the energy is
shared with each bulb so
the more bulbs you add,
the dimmer the light gets.
In the parallel circuit B,
each bulb has their own
path to the batteries so
they do not share the
voltage.
CIRCUIT B WOULD HAVE
BRIGHTER BULBS. In the
series circuit B, when you add
batteries the voltage of the
battery is added together
because there is only on path.
In the parallel circuit A,
electricity takes the shortest
path to the first battery only.
The second battery acts as a
back up.
CIRCUIT A
WOULD HAVE
BRIGHTER BULBS.
In circuit B, the
polarity if wrong
and the bulb will
not light.

CIRCUIT B WOULD
HAVE BRIGHTER
BULBS. In the series
circuit B, when you
add batteries the
voltage of the battery
is added together
because there is only
on path. In the
parallel circuit A,
electricity takes the
shortest path to the
first battery only. The
additional battery acts
as a back up.
CIRCUIT A WOULD
HAVE BRIGHTER BULBS.
In a series circuit, when
you add batteries the
voltages add together
because there is only
one path. Since there
are more batteries in
circuit A, there is more
energy going to the
light bulb.
The brightness of the
bulbs are the same.
Electricity takes the
shortest, easiest path
and in a parallel circuit
energy is taken from the
closest battery. The
voltage does not add
together.
CIRCUIT B WOULD HAVE BRIGHTER BULBS. In the
series circuit A, when you add bulbs the energy is
shared with each bulb so the more bulbs you add,
the dimmer the light gets. In the parallel circuit B,
each bulb has their own path to the batteries so
they do not share the voltage.
