Your science teacher presents you with a circuit model that contains five light bulbs, a switch, and a 1.5-volt battery. The wires of the circuit are hidden from your view so that you cannot see how the bulbs are connected to the battery. How could you determine the type of circuit used in the model? (AKS 10b / DOK 3)
A.
If you unscrew one bulb and all the other bulbs stay lit, it is a parallel circuit because each bulb in a parallel circuit has its own path to the battery.
B.
If you unscrew one bulb and all the other bulbs stay lit, it is a series circuit because all bulbs in a series circuit have to share the same current.
C.
If all the bulbs are equal brightness, it is a parallel circuit because each bulb in a parallel circuit has its own path to the battery.
D.
If all the bulbs are equal brighness, it is a series circuit because each bulb in a series circuit has to share the same current.
