What is a good thing about series circuit?

There's not much good things about a series circuit, but here's one that i know about. A series circuit has more than one power source or output device. It uses a single path to connect all the devices. An advantage of a series circuit is that you can add more power devices, such as more batteries, and increase the force of the output. This will give you more power.

P.S. If you wanna see a bad thing about a circuit, then just type, What is a bad thing about a series circuit? in that box thingy.
