Because, unlike a simple string of lights in a series circuit, these are all arranged in a parallel circuit. And you can think of a parallel circuit as having several different routes that all run ...

Series and Parallel Circuit Series and parallel circuits are two fundamental configurations in electrical circuits, each with distinct characteristics that affect how electricity flows through them.

However, this is a great time to look at the difference between series and parallel circuits. A Simple Circuit Just about the simplest circuit you can create uses just one battery and one light bulb.
