How to read electrical diagrams. A line represents a wire. Power comes out of l2 to the switch which when open breaks the circuit preventing current flow and when closed ties the left and the right terminals of the switch together allowing current flow. Electrical diagrams are typically created by electrical engineers. Knowing how to read circuits is a very useful skill that will help you out all the time. For example in our diagram 2111e means that contact goes to 21 st page and the junction of 11. Resources and going further.
To begin understanding how to read and understand electrical circuit diagrams take our basic circuit and draw it out as it would physically be wired. Follow a circuit with your finger to see where it goes and what it does. Learn to read electrical and electronic circuit diagrams or schematics. This instructable will show you exactly how to read all those confusing circuit diagrams and then how to assemble the circuits on a breadboard. The electrical wiring diagram consists of two types such as a single line wiring diagram and a multi line wiring diagram. We show our ac power source on the left with l1 and n coming out of it our switch to the top and our light to the left.
Check out some of these tutorial to practice your new found schematic knowledge. In solidworks electrical complex schematics can be created in a matter of minutes and portions of the circuit copied and saved for re use. For all the electronics hobbyist wannabes this is a must read instructable. The box is marked with the numbers and alphabets followed by the page number. In addition to reading this instructable it may be a good idea for you to read my other instructable. Knowing component symbols following nets and identifying common labels.
This method takes time but provides valuable insight into the operations of the circuit how it is connected and the basic design of the product. To read a wiring diagram first you have to know what fundamental elements are included in a wiring diagram and which pictorial symbols are used to represent them. The switch is connected. A list of electrical symbols and descriptions can be found on the electrical symbol page. It is a device that stores electrical energy and usually has. Solidworks electrical comes pre packaged with device libraries containing thousands of symbols 2d footprints and manufacturer parts.
See our engineering essentials page for a full list of cornerstone topics surrounding electrical engineering. Understanding how a schematic works opens up the whole world of electronics to you. A drawing of an electrical or electronic circuit is known as a circuit diagram but can also be called a schematic diagram or just schematic. Circuit or schematic diagrams consist of symbols representing physical components and lines representing wires or electrical. When reading an electrical diagram start at the main power source. The common elements in a wiring diagram are ground power supply wire and connection output devices switches resistors logic gate lights etc.
Repeat this process with all the circuits. See their number is in the horizontal axis and alphabets in the vertical axis. There always exists the method of brute force drafting and then there are intelligent tools to bring your designs to fruition quicker. They are usually represented by zig zag lines with. Resistors are the fundamental components of electrical schematics. Especially if you start messing around with building little electronics projects.
Once you know how to read an electrical schematic the next step is to design your own. Thats all there is to schematic reading. Voltage dividers this is one of the most basic. Wires are used to connect the components. Capacitors have different types that are in common use. Refer to the figure an electrical wiring diagram is surrounded by the rectangular box.
