Question

Electrons carry energy from a battery to a lightbulb.

What happens to the electrons when they reach the lightbulb?
The electrons are emitted as light.
The electrons stay in the lightbulb.
Fewer electrons leave the bulb than enter it.
The electrons are used up.
None of the above.

Answer 1

None of the above.

Step-by-step explanation:

In a lightbulb, electrons at higher potential energy enter the lightbulb and give off that energy as they pass through the bulb. The number of electrons exiting and entering the bulb is the same. As electrons pass through the lightbulb, heat is produced due to the current, this makes the filament of the lightbulb to incandescence, and that is the light we see.

Answer 2

The correct answer among all the other choices is "None of the above." Electrons carry energy from a battery to a light bulb. The electron's potential energy will be converted into light energy. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
