Pictorial schematic diagrams, or graphic circuit diagrams are essentially the same thing with exactly the exact identical purpose, but they use pictures of elements inside the circuit rather than symbols. Again, here's the exact specific circuit (virtually except a control transformer was added and they're using conductors L1 and L3 rather than L1 and L2.
Consider it this way; a circuit structure is any kind of diagram which demonstrates how a circuit operates where the main goal is the appropriate wiring of components and their connection to each other instead of physical place relative to one another or planning prototypes. Nevertheless, in some uses Assessing diagrams can be challenging so take this as overall advice. I have discovered this is especially true when dealing with more complex circuits and electronic equipment. I'm likely to work with a more straightforward but typical industrial circuit since these circuit set ups are exactly the same, but where it is possible to see how each sort of diagram shows the function of the circuit in their own manners.
A design diagram refers to a specific kind of circuit structure which utilizes standard electrical/electronic symbols rather than images to demonstrate how a circuit (or part of it) functions. Below is a normal 3-wire motor controller circuit utilizing a standard momentary stop - start pushbutton channel utilizing a schematic diagram. (Momentary here means the button/switch you trigger will go back to its default place once you let go of this, typically by a spring which compels the button/switch to do this.)
Here is another schematic diagram showing the same circuit, components and connections and it seems different but they both fall into exactly the exact identical category.
Less clutter? I have enough information in every one of these diagrams to know precisely what this circuit does and also where to look for problems. Hope that this helps. ( Note: don't confuse lecture or circuit diagrams together with wiring diagrams; wiring diagrams will usually show images of elements such as the pictorial, and how the entire or part of a circuit has been wired. The distinction is that wiring diagrams usually put an emphasis on real physical location of necessary components relative to each individual that basically tell a layman Just What to do about the wiring. )
Following is a technical version of a schematic diagram called a ladder design. The principle intent of this diagram will be to show the logic (referring to electric management ) of a circuit. This diagram is the one I mostly come across in my line of work, and it is very effective for troubleshooting problems or learning the way the circuit functions. Some circuits are so huge that most types of schematic diagrams have to be read in increments in novel form (typically with coded numbers so that info can be easier found). Again, here is the exact identical precise circuit because the first 2, but looking at it in ladder type.
