2. one bulb will be brighter than the other.
Explain how you know.

20. Slide 12 A B

24. ___________ energy to __________ energy to ___________energy
Battery to wire to bulb
___________ energy
to __________ energy
to ___________energy

25. 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.

26. CIRCUIT A WOULD HAVE BRIGHTER BULBS
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.

27. CIRCUIT A WOULD HAVE BRIGHTER BULBS
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.

28. CIRCUIT B WOULD HAVE BRIGHTER BULBS
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.

29. CIRCUIT B WOULD HAVE BRIGHTER BULBS
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.

30. CIRCUIT B WOULD HAVE BRIGHTER BULBS
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.

31. CIRCUIT A WOULD HAVE BRIGHTER BULBS
CIRCUIT A WOULD HAVE BRIGHTER BULBS. In circuit B, the polarity if wrong and the bulb will not light.

32. Slide 12 A
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. B

33. CIRCUIT A WOULD HAVE BRIGHTER BULBS
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.

34. The brightness of the bulbs are the same
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.

35. CIRCUIT B WOULD HAVE BRIGHTER BULBS
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.
