[Theme Music] Let's keep things simple. There's an enormous ... these equations to work! Here's an example of a circuit with resistors in both series and parallel formations.

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 ...

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.
