• a plastic cap
• a metal screw
• a wooden handle

In a series circuit  with 4 bulbs:

• a switch is never used
• all of the bulbs become dimmer if another bulb is added
• There are many paths for electricity to take
• the remaining 3 bulbs stay lit if one burns out

An example of an insulator is:

• iron
• silver
• copper wire
• rubber

What is the difference between a conductor and an insulator?

• An insulator allows electricity to flow through it easily and a conductor does not
• A conductor allows electricity to flow through it easily and an insulator does not.
• An insulator is magnetic and a conductor is not
• A conductor is magnetic and an insulator is not

What happens to the brightness of the light bulbs in a series circuit when you add more lights.

• Each bulb gets dimmer
• Each bulb remains the same
• Half of the bulbs get dimmer
• Each bulb gets brighter

When switch is turned on the circuit is? 

• Open
• Closed

What kind of circuit is this?

• series
• parallel

What is a switch's function in a circuit?

• to make the current hotter or colder
• turn on and off the flow of current
• the pathway that current flows
• to add more power to the circuit

If bulb 1 burns out, what will occur?

• bulbs 2 and 3 will go out
• bulbs 2 and 3 receive more volts
• bulbs 2 and 3 will stay lit
• nothing will happen

Does this statement best describe a parallel or a series circuit.
 
When more light bulbs are added they all remain bright. 

• Parallel circuit
• Series circuit
