What is a conductor?

•  A material that allows electricity to flow through it.  The circuit is complete. 
• A material that does not allow electricity to flow through.  It stops the flow of electricity.

• Lightbulb burns the brightest in this circuit.
• railroad tracks

An example of an insulator is?

• metal
• plastic
• brass

The circuit that has only one path for electricity to travel around.

• parallel circuit
• series circuit
• no circuit
