When it comes to powering projects there are many different sources of power available. This article aims to help you decide which power source is most suitable for your next project and what considerations you should make.

Main Characteristics of Power Sources

Power sources can include both converters (such as mains adapters) and actual sources of energy (such as batteries).

A power source is the most important component in an electrical circuit because, without a source of power, nothing can be done (even passive elements require an external energy source to push electrons through them).

With the many different types of power sources available, it is important to recognize that each source is unique and has its own applications. The type of source that you choose will almost certainly have consequences to your project which may include how much power you can draw, where your project can be located, and if protection methods are required in the event of electrocution.

A Power Sources Rating Guide

To make choosing and comparing easier, each power source discussed in this article will be scored out of 10 (1 being awful, 10 being great) on the following aspects:
