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
