Pictorial design diagrams, or graphic circuit diagrams are essentially the exact identical thing with the exact same purpose, however they use pictures of components within the circuit rather than symbols. Again, here is the identical specific circuit (virtually except a controller was inserted and they're using conductors L1 and L3 instead of L1 and L2.
Right, Less clutter? I've got enough information in all these diagrams to know just what this circuit does and where to start looking for problems. Hope that this helps. ( Note: do not confuse lecture or circuit diagrams together with wiring diagrams; wiring diagrams will typically demonstrate images of elements like the pictorial, and also the way the entire or part of a circuit will be wired. The distinction is that wiring diagrams usually place an emphasis on actual physical location of necessary elements relative to each other that basically tell a layman Just What to do about the wiring. )
Following is a specialized version of a diagram known as a ladder structure. The principle point of this diagram will be to show the logic (speaking to electric control) of a circuit. This diagram is the one that I mainly come across in my own line of work, and it's very successful for troubleshooting issues or learning the way the circuit works. Some circuits are so huge that most types of schematic diagrams have to be recorded in increments in novel form (normally with coded numbers so that info can be easier found). Again, here's the identical precise circuit as the first 2, however, considering it in ladder type.
Think of it this way; a circuit diagram is any kind of diagram that illustrates the way the circuit operates where the primary goal is that the proper wiring of components and their connection to each other rather than physical place relative to each other or intending prototypes. However, in some applications classifying diagrams can be hard so do this as general advice. I've discovered this is especially true when dealing with more complicated circuits and electronic equipment. I'm going to use a more straightforward but typical industrial circuit since these circuit setups are exactly the same, but where it is possible to see how each type of diagram indicates the operation of the circuit in their own ways.
Here's another schematic diagram demonstrating precisely the same circuit, components and connections and it looks different but they both fall into precisely exactly the exact same category.
A schematic diagram refers to a specific type of circuit diagram that utilizes standard electrical/electronic symbols rather than pictures to show the way the circuit (or part of it) functions. Below is a typical 3-wire motor controller circuit employing a normal short stop stop - start pushbutton channel utilizing a schematic diagram. (Momentary this means the button/switch you activate will go back to its default location once you let go of it, usually by a spring which forces the button/switch to get this done.)
