Pictorial schematic diagrams, or graphic circuit diagrams are basically the same thing with exactly the same function, but they use pictures of elements inside the circuit rather than symbols. Again, here is the same specific circuit (virtually except a control transformer was included and they are utilizing conductors L1 and L3 instead of L1 and L2.
Here's another schematic diagram demonstrating exactly the identical circuit, connections and components and it appears different but they fall into precisely exactly the same category.
A schematic diagram refers to a specific type of circuit diagram which uses standard electrical/electronic symbols instead of images to show how a circuit (or portion of it) functions. Below is a typical 3-wire motor control circuit employing a standard short stop stop - start pushbutton station using a schematic diagram. (Momentary this means that the button/switch you trigger will go back to its default place once you physically let go of this, usually by a spring that forces the button/switch to get this done.)
Less clutter, right? I have enough info in all of these diagrams to know just what this circuit does and where to look for issues. Hope that this helps. ( Note: do not confuse lecture or circuit diagrams with wiring diagrams; wiring diagrams will usually demonstrate images of elements like the pictorial, and how the whole or portion of a circuit has been wired. The difference is that wiring diagrams usually place 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)
Consider it this way; a circuit structure is any kind of diagram that demonstrates the way the circuit functions where the principal objective is the proper wiring of elements and their connection to each other instead of physical place relative to each other or planning prototypes. Nevertheless, in some applications Assessing diagrams can be challenging so consider this as general advice. I've discovered this is particularly true when working with more complicated circuits and electronic equipment. I'm likely to use a more straightforward but average industrial circuit because these circuit set ups are exactly the same, but nevertheless where you can observe how each kind of diagram indicates the purpose of the circuit in their own ways.
Here is a version of a schematic diagram called a ladder design. The main goal of this diagram is to show the logic (referring to electrical control) of a circuit board. This diagram is the one that I mainly come across in my own line of work, and it's very effective for troubleshooting issues or learning the way the circuit functions. Some frequencies are so enormous that many kinds of schematic diagrams need to be recorded in increments from novel form (generally with coded numbers so information can be easier located ). Again, here is the exact same exact circuit since the first two, however, looking at it in ladder form.
