Think of it in this way; a circuit structure is any type of diagram that illustrates the way the circuit functions where the main purpose is the proper wiring of components and their relationship to each other instead of physical place relative to each other or planning prototypes. However, in some uses Assessing diagrams can be difficult so take this as general information. I've discovered this is particularly true when dealing with much more complex circuits and electronics. I'm likely to use a simpler but average industrial circuit since these circuit setups are exactly the same, but where you're able to observe how each sort of diagram indicates the role of the circuit in their own ways.
Following is a version of a diagram known as a ladder diagram. The principle goal of this diagram will be to show the logic (referring to electrical control) of a circuit board. This diagram is the one that I mostly encounter in my line of work, and it's very effective for troubleshooting problems or learning how a circuit functions. Some frequencies are so huge that most kinds of schematic diagrams have to be read in increments from novel form (usually with coded numbers so information can be easier located ). Again, here's the exact identical precise circuit since the first 2, however, looking at it in ladder form.
Less clutter? I have enough info in every one these diagrams to know just what this circuit will do and where to start looking for problems. Hope this helps. ( Note: don't confuse lecture or circuit diagrams with wiring diagrams; wiring diagrams will usually demonstrate pictures of components like the pictorial, and how the whole or portion of a circuit is wired. The difference is that wiring diagrams typically place an emphasis on real physical location of necessary elements relative to each individual that basically tell a layman Just What to do about the wiring. )
Here's another schematic diagram demonstrating the identical circuit, connections and components and it looks different but they fall into precisely the exact same category.
Pictorial design diagrams, or pictorial circuit diagrams are essentially the same thing with the identical purpose, however they use pictures of elements within the circuit rather than symbols. Again, here's the exact precise circuit (virtually except a control transformer was added and they're utilizing conductors L1 and L3 instead of L1 and L2.
A schematic diagram refers to a specific sort of circuit diagram which uses standard electrical/electronic symbols instead of images to demonstrate how a circuit (or part of it) functions. Below is a typical 3-wire motor controller circuit using a standard short stop halt - start pushbutton station employing a schematic diagram. (Momentary this means the button/switch you activate will return to its default position once you let go of this, typically by a spring which forces the button/switch to get this done.)
