Lightbulb connected in series with two others in parallel
Mientras se presiona el pulsador P, la corriente de la pila llega a las 3 bombillas, encendiendo con mayor intensidad la bombilla B1 con respecto a B2 y B3 que lucen poco debido a que por B1 pasa el doble de corriente eléctrica que por B2 y B3.
If one of the two lightbulbs fuses or is removed, the other keeps shining. Why?

Application with minikits:

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:

Se utiliza 1 portapilas, 4 minikits y 6 latiguillos de conexión.
