• True
• False

Which statement is true?

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

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

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

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

What kind of circuit is this?

• Series
• Consecutive
• Parallel
• Training

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.
• The same current flows through all three light bulbs.
• It uses a single battery.
• The electrical current has more than one path to flow through

In a Series circuit the more lightbulbs you add the brighter they get 

• False 
• True 

Which of the following statements is FALSE?

• Wire length and size never matter when considering resistance.

• Wires are made of conductive metals like copper.

• Wires offer low resistance to the flow of electricity.

• Most wires have a color coating for insulation and identification.

Which of the following would all be connected in a series?

• A lamp and a switch on the wall controlling it.

• String of holiday lights in which you can take a bulb out and the rest of the lights stay lit.

• Two lamps in different rooms of a house.

• The air conditioner and microwave oven in your home.

Which of the following would all be connected in parallel?

• A lamp an a switch on the wall controlling it.

• The streetlamps in your neighborhood.

• A string of holiday lights that all go out if a bulb is missing.

• None of the above.

It is better to connect lamps in a parallel circuit configuration when...

• the power source can supply enough current but not enough voltage to light them all

• if one bulb burns out, you want the others to stay lit

• you are also adding switches to control each lamp separately

• all of the above
