What connects all the parts of an electric circuit together? An example is a wire. 

• Electron

• Transformer

• Conductor

• Source

Look at the picture to determine which statement is true.

• The light bulb will light up because the circuit is closed.

• The light bulb will not light up because the circuit is broken.

• The light bulb will light up because the circuit is open.

• The light bulb will light up because the insulator is closed.
