This Science quiz is called 'Electrical Circuits 1' and it has been written by teachers to help you if you are studying the subject at middle school. Playing educational quizzes is a fabulous way to learn if you are in the 6th, 7th or 8th grade - aged 11 to 14.
Electrical circuits are closed paths for currents to flow and they are usually made of components joined by wires. Have you ever counted how many electrical items you have in your house?
