A schematic diagram refers to a particular type of circuit design that utilizes standard electrical/electronic symbols rather than images to show how a circuit (or a portion of it) works. Below is a standard 3-wire motor control circuit utilizing a typical short stop stop - start pushbutton channel using a schematic diagram. (Momentary this means the button/switch you trigger will return to its default location once you let go of it, typically by a spring which forces the button/switch to get this done.)
Right, less mess? I have enough information in each one of these diagrams to know exactly what this circuit will do and also where to search for problems. Hope this helps. ( Note: do not confuse lecture or circuit diagrams with wiring diagrams; wiring diagrams will usually demonstrate images of elements such as the pictorial, and the way the entire or portion of a circuit is wired. The difference is that wiring diagrams typically put an emphasis on real physical location of necessary elements relative to each other that basically tell a layman Just What to do about the wiring)
Pictorial schematic diagrams, or graphic circuit diagrams are basically the identical thing with exactly the exact identical purpose, but they use images of components within the circuit instead of symbols. Again, here's the exact identical exact circuit (virtually except a control transformer was added and they're utilizing conductors L1 and L3 instead of L1 and L2.
Here's another schematic diagram demonstrating the identical circuit, connections and components and it looks different but they both fall into exactly the identical category.
Think of it this way; a circuit diagram is any kind of diagram that illustrates how a circuit operates where the major goal is the proper wiring of elements and their relationship to each other rather than physical location relative to one another or intending prototypes. Nonetheless, in some applications Assessing diagrams can be challenging so choose this as general advice. I have found this is particularly true when working with more complicated circuits and electronic equipment. I'm going to work with a more straightforward but average industrial circuit because these circuit set ups are exactly the same, but nevertheless where you can see how each type of diagram shows the function of the circuit in their own ways.
Here is a version of a design diagram known as a ladder structure. The most important intent of this diagram will be to demonstrate the logic (speaking to electric management ) of a circuit board. This diagram is the one that I mainly encounter in my line of work, and it is very effective for troubleshooting problems or learning how a circuit functions. Some circuits are so enormous that most types of schematic diagrams have to be read in increments from novel form (typically with coded numbers so info can be easier found). Again, here's the identical precise circuit as the first two weeks, however, considering it in ladder type.
