Question

in the parallel circuit in the picture, what will happen if lightbulbs a and c burn out? lightbulb b will turn off. lightbulb b will stay lit. all of the bulbs will stay on.

Explanation:

In a parallel circuit, each component (lightbulb here) has its own independent path for current. So if one or more components (like A and C) fail (burn out), the other components (like B) still have their own complete circuit path. Thus, the current can still flow through B's path, keeping B lit.

Answer:

Lightbulb B will stay lit.
