Pictorial design diagrams, or pictorial circuit diagrams are essentially the identical thing with the identical purpose, but they use pictures of elements within the circuit instead of symbols. Again, here's the exact same exact circuit (virtually except a controller was inserted and they are using conductors L1 and L3 rather than L1 and L2.
Right, Less clutter? I've got enough information in each these diagrams to know precisely what this circuit will do and also where to start looking for problems. Hope that this helps. ( Note: don't confuse lecture or circuit diagrams with wiring diagrams; wiring diagrams will usually show images of components such as the pictorial, and how the entire or portion of a circuit is 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. )
Here's another schematic diagram demonstrating exactly the identical circuit, components and connections and it looks different but they both fall into the identical category.
Consider it this way; a circuit diagram is any kind of diagram which illustrates the way the circuit functions where the major purpose is that the proper wiring of components and their connection to each other instead of physical location relative to each other or intending prototypes. Nevertheless, in some uses classifying diagrams can be hard so accept this as overall advice. I have discovered this is especially true when dealing with much more complicated circuits and electronics. I'm going to use a simpler but typical industrial circuit because these circuit setups are exactly the same, but where you can observe how each kind of diagram shows the operation of the circuit in their own manners.
A schematic diagram refers to a specific kind of circuit design which uses standard electrical/electronic symbols instead of images to demonstrate the way the circuit (or part of it) works. Below is a normal 3-wire motor control circuit using a normal short stop stop - start pushbutton station working with a schematic diagram. (Momentary here means that the button/switch you trigger will return to its default place once you let go of it, typically by a spring which compels the button/switch to get this done.)
Here's a specialized variant of a diagram called a ladder structure. The principal purpose of this diagram will be to demonstrate the logic (referring to electric management ) of a circuit board. This diagram is the one that I mainly encounter in my own line of work, and it is extremely effective for troubleshooting issues or learning how a circuit works. Some frequencies are so huge that most types of schematic diagrams need to be read in increments from book form (usually with coded numbers so information can be simpler found). Again, here's the same precise circuit as the first 2, but looking at it in ladder form.
