A schematic diagram refers to a specific sort of circuit design which uses standard electrical/electronic symbols instead of pictures to show the way the circuit (or portion of it) works. Below is a normal 3-wire motor controller circuit employing a standard momentary stop - start pushbutton channel using a schematic diagram. (Momentary here means the button/switch you trigger will go back to its default location once you let go of it, typically by a spring which forces the button/switch to get this done.)
Pictorial schematic diagrams, or pictorial circuit diagrams are basically the identical thing with the identical function, but they use pictures of components inside the circuit instead of symbols. Again, here's the identical specific circuit (almost except a controller was added and they're using conductors L1 and L3 instead of L1 and L2.
Here's a specialized version of a schematic diagram known as a ladder design. The most important goal of this diagram will be to show the logic (speaking to electrical management ) of a circuit board. This diagram is the one I mostly come across in my line of work, and it's very successful for troubleshooting issues or learning how a circuit functions. Some frequencies are so huge that many kinds of schematic diagrams need to be recorded in increments in novel form (generally with coded numbers so information can be simpler found). Again, here's the same specific circuit since the first two, however considering it in ladder type.
Here's another schematic diagram demonstrating the identical circuit, connections and components and it seems different but they both fall into exactly the same category.
Think of it in this way; a circuit diagram is any kind of diagram that illustrates the way the circuit functions where the main purpose is the appropriate wiring of components and their connection to each other instead of physical location relative to one another or planning prototypes. Nonetheless, in some uses Assessing diagrams can be hard so choose this as general information. 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 since these circuit setups are the exact same, but yet where you're able to see how each type of diagram indicates the function of the circuit in their own manners.
Right, Less mess? I have enough info in all of these diagrams to know just what this circuit will do and where to look for issues. Hope that this helps. ( Note: do not confuse circuit or schematic diagrams together with wiring diagrams; wiring diagrams will often show images of components such as the pictorial, and how the whole or portion of a circuit has been wired. The difference is that wiring diagrams typically put an emphasis on actual physical location of necessary components relative to each individual that essentially tell a layman exactly what to do about the wiring)
