Lightbulb connected in series with two others in parallel
While the pushbutton P is pressed, the voltage of 4,5 V reaches lightbulbs B1 and B2, and they turn on.
If one of the two lightbulbs fuses or is removed, the other keeps shining. Why?
Application with minikits: We use 2 battery holders, 4 minikits, and 4 connection cables. Mark on the scheme each cable that we place.
LIGHTBULB CONNECTED IN PARALLEL WITH TWO OTHERS IN SERIES
While the pushbutton P is pressed, the voltage of 4,5 V reaches the three lightbulbs and they turn on.
Lightbulbs B2 and B3 shine less because 4,5 V is applied to B1, and half is applied to B2 and B3.
If the lightbulb B1 fuses or is removed, b2 and b3 keeps shining. If the lightbulb B2 fuses or is removed, only B3 turns off. If the lightbulb B3 fuses or is removed, only B2 turns off.
Application with minikits: We use 1 battery holder, 4 minikits, and 4 connection cables.
