When the battery power goes out, it will choose the route to follow.

There is electrical equipment on every trail. Many paths are divided into several groups to follow and each path does not interfere with each other. If we put two bulbs in two separate paths, we can make the two small bulbs light up together or one light and one not. Such a circuit is called a parallel circuit.
