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. Figure 1: A bulb can form part of an electric circuit.

You will also learn how electromagnets work and how to make a simple electromagnet. You will learn how to draw circuit diagrams. Figure 1.1: Voltage V1 is the electrical potential gained by moving charge Q1 in an electric field. You should also be able to get a rough idea of how the circuit works, just by looking at the schematic. In this chapter, you will learn what an electric circuit is and how to connect all the parts of an electric circuit. In an electronic circuit, the electromagnetic problem of voltages at arbitrary points in space is typically simplified to voltages between nodes of circuit components such as resistors, capacitors, and transistors. It’s not enough to just be able to recognize the components in a schematic. Open Web Editor Share Circuits Upload and share your circuit designs. Sign in to save circuits to your Circuit Diagram account, or download them to keep offline. Web Editor Design circuits online in your web browser. The main goal of this tutorial is to show you the essential schematic components you should know. Simulate Use the built-in circuit simulator (BETA) or export your designs to netlist format. Each physical component (i.e resistor, capacitor, transistor) has a unique schematic symbol. More circuit diagram templates are available inside the circuit diagram tool. To start developing your schematic reading abilities, it’s important to memorize the most common schematic symbols. Simply click Edit on a template and then customize it to fit your needs.

The ability to read electrical schematics is a really useful skill to have.
