Consider it in this way; a circuit diagram is any sort of diagram which illustrates how a circuit operates where the most important objective is that the proper wiring of elements and their relationship to each other instead of physical location relative to each other or planning prototypes. However, in some applications classifying diagrams can be challenging so do this as general advice. I have found this is especially true when working with much more complicated circuits and electronic equipment. I'm likely to use a simpler but typical industrial circuit since these circuit setups are exactly the same, but nevertheless where you're able to see how each kind of diagram shows the function of the circuit in their own manners.
Here's another schematic diagram showing the identical circuit, components and connections and it appears different but they both fall into precisely exactly the identical category.
Right, less clutter? I've got enough info in each one these diagrams to know just what this circuit does and also where to look for problems. Hope that this helps. ( Note: do not confuse circuit or schematic diagrams with wiring diagrams; wiring diagrams will typically show images of components like the pictorial, and the way the whole or portion of a circuit is wired. The distinction is that wiring diagrams generally place an emphasis on actual physical place of necessary components relative to each individual that basically tell a layman Just What to do about the wiring)
Here is a version of a schematic diagram. The main intention of this diagram will be to demonstrate the logic (referring to electric control) of a circuit board. This really is the one that I mostly come across in my own line of work, and it's very successful for troubleshooting problems or learning how a circuit functions. Some frequencies are so huge that most types of schematic diagrams have to be recorded in increments from book form (normally with coded numbers so info can be simpler located ). Again, here is the same specific circuit as the first 2, however, considering it in ladder shape.
A schematic diagram refers to a particular sort of circuit design that utilizes standard electrical/electronic symbols instead of pictures to demonstrate the way the circuit (or part of it) works. Below is a normal 3-wire motor control circuit using a normal momentary halt - start pushbutton station utilizing a schematic diagram. (Momentary here means that the button/switch you trigger will return to its default position once you physically let go of it, usually by a spring that forces the button/switch to get this done.)
Pictorial schematic diagrams, or pictorial circuit diagrams are basically the identical thing with exactly the exact identical purpose, but they use images of components inside the circuit rather than symbols. Again, here is the identical precise circuit (almost except a control transformer was inserted and they are using conductors L1 and L3 instead of L1 and L2.
