Here's another schematic diagram demonstrating the same circuit, components and connections and it looks different but they both fall into precisely the same category.
Think of it in this way; a circuit diagram is any sort of diagram which illustrates how a circuit operates where the principal purpose is that the proper wiring of elements and their relationship to each other rather than physical place relative to one another or planning prototypes. Nevertheless, in some applications classifying diagrams can be difficult so take this as overall advice. I have found this is especially true when dealing with more complicated circuits and electronics. I'm going to work with a more straightforward but typical industrial circuit since these circuit set ups are the exact same, but yet where it is possible to see how each kind of diagram shows the purpose of the circuit in their own ways.
Right, less clutter? I have enough information in each of these diagrams to know just what this circuit will do and where to search for problems. Hope that this helps. ( Note: don't confuse lecture or circuit diagrams with wiring diagrams; wiring diagrams will often demonstrate pictures of components like the pictorial, and also the way the whole or portion of a circuit will be wired. The distinction is that wiring diagrams typically place an emphasis on actual physical location of necessary components relative to each other that basically tell a layman exactly what to do concerning the wiring. )
A schematic diagram refers to a specific type of circuit design that uses standard electrical/electronic symbols instead of pictures to demonstrate the way the circuit (or a part of it) functions. Below is a standard 3-wire motor controller circuit using a normal short stop halt - start pushbutton channel utilizing a schematic diagram. (Momentary this means that the button/switch you activate will return to its default location once you physically let go of this, usually by a spring which forces the button/switch to do this.)
Here is a technical variant of a diagram known as a ladder design. The principal goal of this diagram will be to demonstrate the logic (referring to electric management ) of a circuit board. This really is the one I mainly encounter in my line of work, and it's very effective for troubleshooting problems or learning how a circuit functions. Some circuits are so enormous that many types of schematic diagrams need to be read in increments in book form (usually with coded numbers so that information can be simpler located ). Again, here's the identical exact circuit since the first two, however considering it in ladder form.
Pictorial schematic diagrams, or graphic circuit diagrams are basically the identical thing with exactly the identical purpose, but they use pictures of elements inside the circuit instead of symbols. Again, here's the identical precise circuit (virtually except a controller was included and they're utilizing conductors L1 and L3 instead of L1 and L2.
