Circuits

Which of these changes to the electric circuit will result in the lightbulb lighting up.

• Turning one battery so that it's positive end connects to the other battery's negative end.

• Straightening the wire so the energy can flow more easily.

• Adding a switch and more wire to make the energy flow.

• Making the length of wire the same on both sides of the lightbulb.

In some twinkle light sets, one burned out light means the entire set doesn't work. In others circuits, one burned out lightbuilb will have no effect on the others.

In which of these circuits will the other lightbulbs light up, even if one bulb is burnt out?

• A

• B

• C

• D

• Conductor

• Open Circuit

• Closed Circuit

A closed conducting circle or loop through which current can flow.

• Battery

• Switch

• Energy Source

• Circuit

The path through which an electric current can flow.

• trench

• stream
