DC Power Sourcesĭirect current (DC) power sources provide electric current that flows in a constant direction. Every functional electronic circuit needs to have a DC or AC power source. Power sources supply electrical energy to a circuit in the form of voltage and current. After this article, I recommend reading How to Analyze Circuits, where we discuss more advanced circuit analysis techniques like Kirchhoff’s Current Law and Kirchhoff’s Voltage Law. You should also be able to get a rough idea of how the circuit works, just by looking at the schematic. The ability to read electrical schematics is a really useful skill to have. They’re like a map for building or troubleshooting circuits, and can tell you almost everything you need to know to understand how a circuit works. It’s not enough to just be able to recognize the components in a schematic. An electrical schematic is a diagram that shows how all of the wires and components in an electronic circuit are connected. The main goal of this tutorial is to show you the essential schematic components you should know. Navigate through the New tab and select Electrical Engineering, followed by Basic Electrical in the diagram pane. Step 1: Open a New Canvas Open EdrawMax software and click on File.
