Sorry for answering you late: It has been a very long time I have not surfed on this site, as I was very disappointed by the ways of the mod as a mod. I have to correct my mistakes though.
You are entirely right: I only thought about the problem as a current source problem, neglecting the obviou... (more) |

You may be right. Probably a wrong choice of the example. (more) |

Well, for me "100s of MHz" is already called "MHz range".
The antenna I am dealing with in the thread are usually operated well in the GHz range.
Also, pay attention that 1ns rise time gives something like 300-500MHz frequency content if I'm not wrong (use a convertor to obtain the precise value)... (more) |

A: Inductance vs frequency If your question is theoretical (you are dealing with ideal components), then the answer of Olin is just fine. If it is concrete, that's the answer of Andy. In the concrete case furthermore, I would add that what interest the engineer in general is not only the inductance, but the whole picture, ... (more) |

@Olin. After your action, who would want to leave any comment after downvoting? You create a Meta to make downvotes public, and at the same time act with an unmatched virulence against a person who has duly justified his downvote. You have used incorrectly the upvoting mechanism to fight my downvote,... (more) |

yeah. In classical electromagnetism, the propagation of the energy of an EM wave is materialized by the so-called "Poynting vector" (@Engin.. you can google it for more information). (more) |

I just would like to understand:

Do you really believe that codidact will code this feature and aban... (more) |

@a concern citizen. No need, I think I have the artifact: the line in the experiment has obviously a non negligible inductance. So, when the switch closes, the inductance of the line creates a relatively slow linearly increasing current, which can induce, indeed, a plateau by capacitive coupling in t... (more) |

Hello Elliot. There is an important discussion in Meta about making downvotes public. Since you are here, I'm taking the unusual step of letting you know that. Of course, if you participate to the debate, feel free to downvote my opinion and express a different opinion. (more) |

@a concerned citizen. Thanks for the feedback, really interesting again. I suspect your alleged SUSTAINED plateau is an artifact of the experiment. Of course, everything is continuous in classical physics, but the meaning of what I said is that there should be a small peak, then the current should de... (more) |

A: Let's make all downvotes public I have finally downvoted the post of Andy "Very short answer - get rid of downvotes on answers" despite it is rather close, in some respects, to my own views. Let me clarify myself. I've never said that downvotes are a bad thing by themselves (to be clarified below), but that downvoting without indic... (more) |

| Comment | Post #285921 |
Wow! what a support to Kranulis! I would like to have enjoyed the same support when I was brutally downvoted, without any reason (and without comment). Curiously Andy, you were not here, and even more curiously, Olin, you were much more reserved in defending me. I'm jealous, really.
Also, as you ca... (more) |

I should also add that your vision is perhaps good, but utopic. Trolls, children, vexed persons etc. exist and use to destroy sites if no counter measures are taken. (more) |

I agree with you in principle Andy, and that's why I have make very few downvotes up to now. Nevertheless there are persons that won't do anything after the comments of some other they dislike or so. When you face those persons, there is no time to waste, and a fortiori whenever you know those pers... (more) |

Of course, since they already know this matter. My comment has to be understood as "if they were not already knowing this subject". Anyway, that's not the point. The question is of elementary level, and as such, should be answered in a more detailed way. My opinion is that most newcomers in electron... (more) |

I downvoted this answer because the first half "One reason" -- "3.3V logic level" is hardly understandable for reasonably competent engineers, and certainly sibylline for most students of the level of this question. This answer may be updated by adding schematics or clearer explanations, in which cas... (more) |

In place of asking Lundin if he downvoted you and complaining in your answer, why did you not come to participate to the debate about downvotes in Meta? after all, you are the trigger of this thread. Where are you when your are needed? (more) |

To make downvotes open will not create such discussions: the mods need only to step in when the discussion become ridiculous and to close it.
On the other hand, openness of the critic will highly improve the quality of the content. Also, mods should remove downvotes ridiculously justified, otherwis... (more) |

Completely wrong, I have personally been the target of the troll (I think there is only one currently). Of course, you can discuss 100 years if this is a troll or a regular voter, but the fact is that no one could explain reasonably some downvotes I got. (more) |

A: Let's make all downvotes public I have proposed to fix a threshold of 100 pts to have the rights to downvote, which solves partially the problem of massive downvotes by trolls creating new accounts. This suggestion seems to have receiveid a positive reaction. Nevertheless, I would like to point out that the original suggestion... (more) |

A: Let's make all downvotes public I've upvoted the post of Olin because I think this is obviously better than the current situation. Nevertheless, this does not completely solve the problem of trolls using multiple accounts. I think a minimum of 100 pts to get the rights to downvote would solve it completely, in addition to the sugge... (more) |

I liked the part at 17:30, where he explains how the capacitive coupling between the wires produces current. Interesting. Did you mean this video contradict something in my answer? I don't see, on the contrary. (more) |

So, the restricted number of papers is what is preventing you to agree with me, not the idea itself.
While your argument makes sense, I think it's not the better choice.
Nothing should prevent a good organization of this site, even though we have relatively few material. In contrast to "Photogra... (more) |

@Olin. No, the bullet list are not only the examples. The two first bullets are from the "definition" section. I've listed all what I saw there, just including the examples as they are supposed to provide a more concrete view. If there is such thing a "broader" definition, it is probably more an info...

Hello Monica. Your suggestion is interesting, and I have personally no objection to call this category resources in place of insights (I should even add that I like this suggestion). This would indeed allow even broader articles to be added. Anyway, I think that's only a cosmetic detail, not the main... (more) |

I think your suggestion is of the same order as that of Monica in the previous thread: to change the name of the current category, in order to lower and extend the expectations (actually Monica suggested to change the name of the new proposed category). As I wrote in the answer to Olin, the level of ... (more) |
