Answer:
1.Since you've applied more resistance to your circuit, which reduces the flow of current, both bulbs will become similarly dim when you plug in the second one.
2.Electricity passes through a closed circuit, passing through a filament, causing it to shine brightly in a simple circuit, such as that used in an incandescent light bulb. The filament will melt or blow out if the current is too high, allowing the circuit to open.
3.if the filament melts the circuit will break and there will be no current flowing in the circuit.
