Irene bought a new house and has decided to rewire it. She wants to be able to turn

some lights off and have the others remain lit. What type of circuits should she use and

why?

• She should use parallel circuits because when one light turns off, the other lights remain lit.

• She should use series circuits because when one light turns off, the other lights remain lit.

• She should use parallel circuits because when one light turns off, the others turn off, too.

• She should use series circuits because when one light turns off, the others turn off, too.
