Did you know?
A circuit is the path along which electricity travels. When all parts of the circuit are connected, electricity flows. A break anywhere in the circuit stops electricity flowing. In one position, the switch breaks the circuit. When that happens, the electricity stops flowing, and there’s no music. In the other position, the switch completes the circuit. When that happens, the electricity flows, and music blasts!
