Answer i will make ! when you remove a bulb from a series circuit, what happens to the other bulbs? they stay lit. they go out.

Using an example like Christmas lights, I would say yes because normally a lot of them would go out if one light is broken.

They go out, in a series circuit all of the light bulbs are connected by a single wire, and when the light bulb gets removed it wouldn't be able to transfer the energy to the next light bulb.
