Here is a specialized variant of a diagram. The principle goal of this diagram will be to show the logic (speaking to electrical management ) of a circuit board. This diagram is the one I mainly encounter in my line of work, and it's extremely successful for troubleshooting problems or learning the way the circuit works. Some frequencies are so huge that many types of schematic diagrams have to be recorded in increments in novel form (generally with coded numbers so that info can be simpler located ). Again, here's the exact same exact circuit because the first two, but considering it in ladder form.
A schematic diagram refers to a specific type of circuit structure which utilizes standard electrical/electronic symbols instead of pictures to demonstrate how a circuit (or portion of it) works. Below is a normal 3-wire motor control circuit utilizing a typical short stop stop - start pushbutton station utilizing a schematic diagram. (Momentary this means the button/switch you trigger will go back to its default position once you let go of it, typically by a spring which forces the button/switch to do this.)
Pictorial design diagrams, or graphic circuit diagrams are basically the identical thing with the identical function, but they use images of elements inside the circuit instead of symbols. Again, here's the exact same exact circuit (virtually except a controller was inserted and they are utilizing conductors L1 and L3 instead of L1 and L2.
Less mess? I've got enough info in all of these diagrams to know precisely what this circuit does and also where to look for issues. Hope this helps. ( Note: do not confuse circuit or schematic diagrams together with wiring diagrams; wiring diagrams will often show pictures of components like the pictorial, and also how the whole or part of a circuit will be wired. The distinction is that wiring diagrams generally place an emphasis on actual physical location of necessary components relative to each other that basically tell a layman exactly what to do about the wiring)
Consider it in this way; a circuit diagram is any type of diagram which demonstrates how a circuit operates where the most important goal is that the proper wiring of elements and their connection to each other instead of physical location relative to one another or planning prototypes. Nonetheless, in some uses classifying diagrams can be difficult so take this as overall information. I've found this is particularly true when dealing with more complex circuits and electronic equipment. I'm going to use a more straightforward but typical industrial circuit since these circuit set ups are the exact same, but where you're able to see how each kind of diagram shows the function of the circuit in their own manners.
Here is another schematic diagram showing precisely exactly the identical circuit, connections and components and it seems different but they fall into precisely the same category.
