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.
