Tammy makes a complete simple circuit with one bulb and three batteries. The bulb lights for an instant and then goes out. Why?

• Too much electricity flows through the bulb's filament

• Not enough electricity flows around the circuit

• The batteries are flat

• The batteries are not good

If lamp 1 is unscrewed from its holder, what will happen to lamp 2?

• It will get brighter

• It will stay the same brightness

• It will go out

• Nothing will happen

Why is a bulb brighter when it is powered by two batteries rather than one?

• Because the flow of electricity in the circuit is less

• Because the flow of electricity in the circuit is the same

• Because the flow of electricity in the circuit is greater

• Because the flow of electricity will go backward
