Technology: Rotation Four

On Friday for Tech we made simple circuits and learnt how they work. They work by power from the battery traveling around the circuit. There are two types of circuits,the series circuit,which goes around and if one piece is disconnected the the whole circuit stops and a parallel circuit which means if one is disconnected the circuit keeps going.We have parallel circuits in our houses,here is a diagram:
