In a parallel circuit with three lights on it, one light breaks. What happens to the intensity of the other two lights?

a
they stay the same

b
they get brighter
c
they go out
d
they get dimmer

a) they stay the same

In a parallel circuit, the lights are connected in a way that if one light breaks, the other lights will continue to function independently. Therefore, the intensity of the other two lights will stay the same.
