If you still have more questions, then "áccept" your choice of best answer to the question you asked there and ask a new question, with a link to the first one, explaining what progress you made using the help you got there. Any new questions must be different, to avoid appearing as a duplicate (hence the need to show how you have used the previous answers). Is that more work for you? Yes. Can it take longer overall, asking one at a time, than asking lots of points in one question? Yes. And always avoid causing a chameleon question. | |
| Nov 6, 2023 at 15:36 | comment | added | SamGibson♦ | @bevren15 - Re: "I have asked 6 questions here." Actually I count 12 as some "questions" contained multiple points. "Do I have to open 6 different questions" You don't know that all 6 (or 12) questions will be needed. It depends on the answers to the first question. Any more than one question per post increases your risk of having problems. It depends on the connection between points and the total number. Remember, Stack Exchange is not a forum, it's a Q&A site and we want focused questions. Best is to ask a single question with a single point, whose answer you have carefully researched... | |
| Nov 6, 2023 at 13:58 | comment | added | bevren15 | @SamGibson - Thank you for the guidance on the rules. For example, I have asked 6 questions here. Do I have to open 6 different questions for each of them? | |

Rollback to Revision 4 - this rollback has been done to stop the question becoming a "chameleon question" as it has already received answers, so expanding it is no longer allowed.

| Nov 6, 2023 at 13:50 | comment | added | SamGibson♦ | (cont'd) Please reconsider how to write any new questions separately, one at a time (waiting for each new question to be completed before asking another one), without overlap. You can link to this question for context, but any new question must be self-contained and not rely on people reading this one too. Thanks. | |
| Nov 6, 2023 at 13:50 | comment | added | SamGibson♦ | (cont'd) You seem to be having problems using the site as you asked too many points in one question, which can lead to some being answered & some not. That breaks the intended use of this site - one question per topic, ideally. While it may not be possible to stick to that when there are very closely related points within a question, it is up to you when asking to minimise the "breadth" (i.e. be specific) both to avoid the question possibly being closed as "needs focus" and so that it can be more easily recognised by other people in future as applying to their question too. | |
| Nov 6, 2023 at 13:50 | comment | added | SamGibson♦ | @bevren15 - Hi, (a) As you're new here, please see the site rules in the tour & help center as they differ from typical forums. (b) You must not keep expanding the question after receiving an answer. Doing so makes answers look wrong / incomplete as they no longer address the changed question. Search for the term "chameleon question" on Meta Stack Exchange. Therefore I have "rolled-back" your question to the state where it was answered. | |

| Nov 6, 2023 at 12:48 | comment | added | Andy aka | Just start a new question about what folk think about using the little transformer generally. It's not about the questions you have raised in this thread. It's about getting feedback as to whether folk think the little transformer is a reliable part to use generally on any design. | |

Added a new question about the connection of R1 (question 7)

| Nov 6, 2023 at 11:40 | comment | added | bevren15 | Sorry, I'm new here. Can't comment on this thread anymore? Should I reopen the question. Is there a button where I can quote you? | |
| Nov 6, 2023 at 11:35 | comment | added | Andy aka | I would ask a brand-new question on this particular part and get others to comment to. You can quote what I'm saying. | |
| Nov 6, 2023 at 11:32 | comment | added | bevren15 | I'm just trying to understand the logic. For example, you mentioned that you don't like the value 1000:1000. If I can find out why you don't like it based on your experience, that would help me a lot. You said it's not a CT. Again, if you share your experience on this subject, it will be clearer in my mind. I am grateful for your help. | |

| Nov 6, 2023 at 10:58 | comment | added | Andy aka | -->Where is there any reasonable evidence that the manufacturer has a recognized quality system in place? Is the device sold through a reputable distribution network for electronic components? And, the fact that you are asking questions about what the device might be with there being no clear-cut and unambiguous answers provided in the pdf data sheet (that also doesn't have a revision number or other form of identification to tell whether it has been updated). It's about quality assurance. | |
| Nov 6, 2023 at 10:24 | comment | added | bevren15 | What are you not convinced about? This circuit is sold on the market to measure 80-250V AC Main line with Arduino. What made you doubt here? How do you know if this is a current transformer or a voltage transformer? | |
| Nov 6, 2023 at 10:18 | comment | added | Andy aka | It shows it with 1000 turns on the primary and same for the secondary. It's up to you to convince yourself that it's suitable for your needs. For me, I'm not convinced. | |
| Nov 6, 2023 at 10:04 | comment | added | bevren15 | I did some research for the ZMPT101B. Although it says voltage transformer in the introduction, the description states that it is a current transformer. See innovatorsguru.com/zmpt101b How do we know if it's not a current transformer? What would be the difference? | |

| Nov 6, 2023 at 9:04 | comment | added | Andy aka | Why we cannot arbitrarily increase the burden resistor for a Current Transformer. And please note that despite you saying it is in your words, the transformer is not a CT. | |
