Consider it in this way; a circuit diagram is any kind of diagram that demonstrates how a circuit functions where the most important purpose is that the proper wiring of elements and their relationship to each other instead of physical location relative to one another or planning prototypes. Nonetheless, in some applications Assessing diagrams can be hard so do this as overall advice. I've found this is especially true when working with much more complicated circuits and electronics. I'm going to use a simpler but typical industrial circuit since these circuit setups are the exact same, but where you can observe how each sort of diagram shows the operation of the circuit in their own ways.
Right, much less clutter? I have enough info in all these diagrams to know exactly what this circuit does 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 show pictures of elements like the pictorial, and also the way the entire or part of a circuit has been wired. The difference is that wiring diagrams typically place an emphasis on real physical location of necessary components relative to each other that basically tell a layman exactly what to do about the wiring)
Pictorial design diagrams, or pictorial circuit diagrams are basically the same thing with exactly the exact same function, but they use pictures of elements within the circuit rather than symbols. Again, here's the exact exact circuit (virtually except a control transformer was included and they're using conductors L1 and L3 instead of L1 and L2.
A schematic diagram refers to a specific kind of circuit structure which utilizes standard electrical/electronic symbols instead of pictures to show the way the circuit (or part of it) works. Below is a standard 3-wire motor control circuit using a typical short stop halt - start pushbutton station working with a schematic diagram. (Momentary this means the button/switch you activate will return to its default place once you let go of it, usually by a spring that compels the button/switch to get this done.)
Here's another schematic diagram showing exactly the identical circuit, components and connections and it seems different but they fall into the exact identical category.
Here's a specialized version of a diagram. The principal intent of this diagram is to show the logic (speaking to electric management ) of a circuit board. This really is the one I mostly come across in my line of work, and it's extremely effective for troubleshooting problems or learning the way the circuit works. Some frequencies are so huge that many kinds of schematic diagrams need to be recorded in increments in novel form (normally with coded numbers so info can be easier located ). Again, here's the same specific circuit as the first 2, however considering it in ladder type.
