A big shout out to Mason McCoy, who found this resource while working on his Boy Scout Electronics Merit Badge and shared it with our club to use on this website. It’s an excellent article by Mark Houlahan for Speedway Motors Academy, and while it’s especially for kids, it’s also good for anyone new to electronics or ham radio.
“Electronic circuits are simply pathways that transmit electric current, or moving electricity. These circuits make it possible for lights and appliances to work. Electric circuits have to have a source of power, wires that the electricity flows through, and a device that uses the electricity. These three parts have to be connected directly for the electric current to flow.”
Read the rest of the article to learn more about these parts, how they work together, closed and open circuits, and measuring electricity:

At the end of this article, there is also a treasure trove of additional links for kids who want to learn more about electricity and electric circuits, including some do-it-yourself projects.
