| Dec 19, 2021 at 22:32 | comment | added | Circuit fantasist | jonk, Exhaustive analysis of the topic written in an amazing way... I completely agree that, at the stage of understanding, circuit diagrams should be cleared of unnecessary (for this purpose) details; they must be conceptual (containing only the most necessary elements to implement the idea). Only then can details be added. I will be happy to follow your TEK link... | |
| Dec 19, 2021 at 21:58 | comment | added | jonk | @Circuitfantasist What I write here is, again, about understanding. In many practical schematics, though, they are littered with IC bypass caps and heavy busing must be annotated, as well as starred power supply arrangements, to indicate special needs in laying out a board. So that would be yet another purpose. It detracts from understanding to have all those bypass caps present and it detracts from understanding to see starring of power supply rails and grounds (except for understanding why that aspect is needed.) Anyway, different horses for different courses (English saying.) | |
| Dec 19, 2021 at 21:54 | comment | added | jonk | @Circuitfantasist So I kind of think that there are different purposes for schematics. A schematic cannot serve all purposes equally well. There are wiring diagram purposes, which are for those wishing to just wire it up but don't need to understand it. So a "maker" schematic would be entirely different. There would also be a schematic to help someone identify, better, KVL loops to use in mesh. And I agree that for some it would be better to keep the voltage sources and wiring. So that could be served better by yet another set of rules. Finally, for understanding, I think the above is right. | |
| Dec 19, 2021 at 21:53 | comment | added | jonk | @Circuitfantasist For some, showing the voltage source does help to "see" the loop. I agree. However, it's also quite simple to still perform the KVL equation straight off of such a diagram. You just start at either end and work towards the other end. The only issue is "imagining" the voltage source as completing the loop so that you can find loops. But with a little practice, that starts to come more naturally. That said, my goal here is in understanding schematics. Not in performing KVL math. Understanding something doesn't necessarily mean doing the KVL, which is just math. | |
| Dec 19, 2021 at 21:23 | comment | added | Circuit fantasist | Dear jonk, There is a lot of philosophy in what you have written... and I share most of it. I just want to add one of my views on the need to draw power rails and the power supplies themselves. This is necessary when, for the purpose of understanding and explaining, we want to show the full current paths (loops). See, for example, my last answer about where input bias currents flow and my paper about how to visualize currents in circuits. | |

| Dec 19, 2021 at 15:39 | comment | added | winny | Your English is fine but shouting is considered bad form. | |
| Dec 19, 2021 at 15:12 | comment | added | user1006899 | thank you @jonk for the concept you tried to explain me with your best efforts | |
| Dec 19, 2021 at 15:04 | comment | added | user1006899 | @winny sorry if i am mistaken in writing as my english is not so strong but if you felt like this then I am really very sorry. sorry for disappointing you | |
| Dec 19, 2021 at 14:34 | comment | added | winny | @user1006899 WHY ARE YOU SHOUTING? | |
| Dec 19, 2021 at 11:17 | comment | added | jonk | @user1006899 My apologies, then. I'm off to bed. Perhaps someone else will be able to provide a more helpful response. If I can think of something tomorrow, I may add it then. | |
| Dec 19, 2021 at 11:13 | comment | added | user1006899 | actually it becomes harder for me to solve such open circuits and having ground connections . It will be easy for me if the diodes are replaced with short circuit or open circuit in a closed loop | |
| Dec 19, 2021 at 10:53 | comment | added | jonk | @user1006899 All I did was to simplify the schematic. This makes it a little easier to apply whatever rules you want to try, including those steps you mention. If you try to apply them and if I understand your attempt then I'll try to respond usefully. That said, I'm off to bed as well. So I may not be able to respond until I wake up. | |
| Dec 19, 2021 at 10:46 | comment | added | user1006899 | i think it's too big to understand isn't there any other method like the steps of assuming enforcing analyzing . it's very hard for a student to understand new thing with such a long method | |
| Dec 19, 2021 at 10:37 | comment | added | jonk | @user1006899 The down arrow, if we are taking about the same thing, is an indicator for ground or the zero volt reference point. | |
| Dec 19, 2021 at 10:36 | comment | added | Mike | Yes the arrow is ground | |
| Dec 19, 2021 at 10:30 | comment | added | user1006899 | is my assumption correct or not | |
| Dec 19, 2021 at 10:28 | comment | added | user1006899 | DOES THIS ARROW MEAN GROUND | |
