Think of it this way; a circuit structure is any sort of diagram which illustrates how a circuit operates where the main objective 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 applications classifying diagrams can be difficult so do this as overall advice. I've found this is especially true when dealing with more complicated circuits and electronics. I'm likely to work with a simpler but typical industrial circuit since these circuit set ups are the exact same, but where you can observe how each kind of diagram indicates the function of the circuit in their own manners.
Here's another schematic diagram showing the identical circuit, connections and components and it seems different but they both fall into exactly the same category.
Right, Less mess? I've got enough info in each of these diagrams to know just what this circuit does and also where to search for problems. Hope that this helps. ( Note: don't confuse lecture or circuit diagrams together with wiring diagrams; wiring diagrams will typically show images of components such as the pictorial, and how the entire or portion of a circuit will be wired. The distinction is that wiring diagrams usually place an emphasis on real physical location of necessary elements relative to each other that basically tell a layman exactly what to do concerning the wiring. )
Here is a technical variant of a diagram. The main intention of this diagram will be to show the logic (speaking to electrical management ) of a circuit. This really is the one I mainly encounter in my line of work, and it's extremely successful for troubleshooting issues or learning how a circuit works. Some frequencies are so huge that many types of schematic diagrams need to be read in increments from novel form (normally with coded numbers so that information can be simpler located ). Again, here's the exact identical precise circuit because the first two, however, looking at it in ladder type.
Pictorial design diagrams, or graphic circuit diagrams are essentially the identical thing with exactly the identical function, however they use images of components inside the circuit rather than symbols. Again, here's the same specific circuit (virtually except a controller was included and they are using conductors L1 and L3 rather than L1 and L2.
A schematic diagram refers to a particular sort of circuit design which uses standard electrical/electronic symbols instead of images to show how a circuit (or portion of it) works. Below is a normal 3-wire motor control circuit using a typical momentary stop - start pushbutton station working with a schematic diagram. (Momentary here means that the button/switch you activate will go back to its default position once you let go of this, typically by a spring which compels the button/switch to get this done.)
