battery, two switches, and 5 LED light bulbs. Electrical energy will be transformed into light energy when switch number two is closed.

Select the TWO correct lights that will light up when switch two is closed.

Multiple Choice

Which of the following best describes what happens in a parallel circuit if one component stops working?

• The entire circuit stops working.
