Consider it this way; a circuit diagram is any type of diagram that demonstrates how a circuit operates where the most important purpose is that the appropriate wiring of elements and their relationship to each other instead of physical location relative to each other or intending prototypes. Nevertheless, in some uses Assessing diagrams can be challenging so do this as overall advice. I've found this is particularly true when working with much more complex 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 see how each sort of diagram shows the function of the circuit in their own manners.
Pictorial schematic diagrams, or pictorial circuit diagrams are basically the exact identical thing with exactly the same purpose, however they use images of elements within the circuit instead of symbols. Again, here's the exact precise circuit (virtually except a control transformer was inserted and they're using conductors L1 and L3 instead of L1 and L2.
Here is another schematic diagram demonstrating precisely the identical circuit, connections and components and it seems different but they fall into exactly the same category.
Right, Less clutter? I've got enough info in all of these diagrams to know exactly what this circuit will do and where to start looking for problems. Hope that this helps. ( Note: do not confuse lecture or circuit diagrams with wiring diagrams; wiring diagrams will usually show images of elements like the pictorial, and also how the whole or portion of a circuit will be wired. The distinction is that wiring diagrams typically place an emphasis on real physical location of necessary components relative to each individual that essentially tell a layman Just What to do about the wiring)
A schematic diagram refers to a particular kind of circuit design that utilizes standard electrical/electronic symbols instead of images to show how a circuit (or portion of it) works. Below is a typical 3-wire motor control circuit utilizing a standard short stop stop - start pushbutton station working with a schematic diagram. (Momentary this means that the button/switch you trigger will go back to its default location once you physically let go of this, typically by a spring that forces the button/switch to do this.)
Here is a technical variant of a design diagram. The main aim of this diagram will be to demonstrate the logic (referring to electric control) of a circuit board. This really is the one that I mainly come across in my line of work, and it is very effective for troubleshooting problems or learning how a circuit functions. Some frequencies are so enormous that many types of schematic diagrams have to be read in increments from novel form (normally with coded numbers so info can be easier located ). Again, here is the exact same specific circuit because the first two, however, looking at it in ladder shape.
