Pictorial design diagrams, or graphic circuit diagrams are essentially the identical thing with exactly the exact identical purpose, however they use images of components within the circuit instead of symbols. Again, here is the same specific circuit (virtually except a control transformer was inserted and they are using conductors L1 and L3 instead of L1 and L2.
Less mess? I have enough info in all of these diagrams to know precisely what this circuit does and where to search for issues. Hope this helps. ( Note: do not confuse circuit or schematic diagrams with wiring diagrams; wiring diagrams will often demonstrate images of components like the pictorial, and also how the whole or part of a circuit has been wired. The difference is that wiring diagrams generally place an emphasis on actual physical location of necessary elements relative to each other that basically tell a layman Just What to do about the wiring)
Think of it in this way; a circuit structure is any kind of diagram that illustrates the way the circuit functions where the main goal is the appropriate wiring of elements and their connection to each other rather than physical location relative to each other or planning prototypes. Nevertheless, in some applications Assessing diagrams can be challenging so choose this as general advice. I have discovered this is especially true when working with more complex circuits and electronic equipment. I'm going to use a more straightforward but typical industrial circuit since these circuit setups are exactly the same, but nevertheless where you can see how each type of diagram indicates the function of the circuit in their own manners.
A schematic diagram refers to a particular kind of circuit structure which uses standard electrical/electronic symbols rather than pictures to show how a circuit (or portion of it) functions. Below is a typical 3-wire motor controller circuit utilizing a standard short stop halt - start pushbutton station using a schematic diagram. (Momentary this means that the button/switch you trigger will return to its default position once you let go of this, typically by a spring that forces the button/switch to do this.)
Following is a specialized variant of a diagram called a ladder design. The principle aim of this diagram will be to demonstrate the logic (referring to electrical management ) of a circuit board. This diagram is the one that I mainly encounter in my own line of work, and it is very successful for troubleshooting issues or learning how a circuit functions. Some frequencies are so huge that most kinds of schematic diagrams need to be read in increments in novel form (normally with coded numbers so information can be simpler found). Again, here is the exact same specific circuit because the first two, however looking at it in ladder form.
Here is another schematic diagram demonstrating precisely the same circuit, connections and components and it seems different but they both fall into precisely the identical category.
