What happens when one bulb is fused when bulb are connected in series?
Similarly one may ask, what happens when one bulb is fused when bulbs are connected in parallel?
If the light bulbs are connected in parallel, the current flowing through the light bulbs combine to form the current flowing in the battery, while the voltage drop is 6.0 V across each bulb and they all glow.
One may also ask, what happens if you connect light bulbs in series? If the three light bulbs are connected in series, the same current flows through all of them, and the voltage drop is 1.5 V across each bulb and that may not be sufficient to make them glow.
Consequently, what happens when a bulb gets fused?
When the filament of a bulb is broken then the bulb is said to be fused. When it gets fused it does not emit light. When the bulb gets fused, the electric current is not allow to pass through the filament and the bulb does not glow because the filament of the bulb is broken.
What happens to the current in a parallel circuit when a bulb breaks?
In a parallel circuit the unbroken bulb would not be affected because the current flow is independent of the broken bulb. In a series circuit the current would go through both bulbs, so if one bulb was broken the good bulb would not light.
