Question;

1.what may happen if you add another bulb to both of your setups? why?

answer:

-when you plug in the second bulb,both will get equally dim, because you have added more resistance to your circuit, which decreases the

flow current.

Question;

2.what may happen if the filament of one of the bulbs in your first setup melts? why?

answer:

-Due to the gap in the filament, electricity is unable to flow through the filaments of fused bulbs, preventing them from lighting up.

Question;
