Just a comment because I don't understand it enough to provide a proper answer: **static electricity** is bad for electronics and is a low-humidity phenomenon, with the problem getting worse the lower the humidity is. (more) |

I think you will find some of those warnings, for good reason, on APC and other more established brands. And the fact that initially it could provide 10-15 minutes of runtime (though likely closer to 200W than 450W) indicates it isn't *that* bad. Amazon Basics tends to be bottom of the line *but* at ...

A: Why would a standby UPS fail to power devices when there's no power outage? Started writing a comprehensive answer, interrupted by some phone calls, finally finished it...and then accidentally clicked to another page and lost it. Arghh!!! So this answer may not be quite as complete/well-written. TL;DR Normal for a UPS with a Low Battery - Replace the Battery or the UP... (more) |

As I understand it, there are multiple ways to force going to the surface, most of which do **not** involve the controller or even the thrusters controlled by the controller. Yes, a single point of failure for a primary system is a big problem, but as I understand it (based on public reports of the d... (more) |

*If the hull became partially flooded* - That is irrelevant. Once you are at high depths, even a partial flood is essentially a death sentence. This is not like a surface boat where you can pump out (or bail out with buckets) water. In fact, this relates to a different problem - they are apparently s... (more) |

I downvoted this answer to show my disagreement, not to indicate it is "bad". But I do disagree, because I think in normal answers the downvotes actually perform a useful service. This is particularly the case if an answer includes either "wrong" information or dangerous instructions. In the case of ... (more) |

Arguably data communications, internet protocol, etc. *could* be on-topic. But saying "evolves binary logic" and "electric signals" is **not** the reason. On that basis, **any** computer (up to a mainframe or entire data center) or electronic device that includes any binary logic (from a series of sw... (more) |

Perhaps the point should be emphasized that "Paper" here does **not** necessarily mean "The same quality and level of innovation needed to publish in a scientific journal".

@coquelicot I agree with your assessment of the question title & contents as stated. But this is a serious safety issue, *and an awful lot of people get the issues confused*, so while it could be (*should* be) more clearly & consistently stated, I think it is still worth answering as (I think) the qu...

@coquelicot I am saying that is the case when there is a **true short circuit**. The problem with water is when you do **not** have a short circuit, but instead have *some* electricity going the wrong way as a ground fault. That is where a regular breaker is nearly useless and GFCI is the solution (a... (more) |

A: Why is the resistance of water so high and still so dangerous? > why water is such a danger for short circuits if the resistance is so high? Actually, the life safety danger for water is NOT a short circuit. In fact, a short circuit in a typical (all values here are US-centric, other areas of the world have somewhat different ways of handling these issues, th... (more) |

Either way, it fits here and hobbyists should not be discouraged. The catch of course is that many consumer electronics are designed to be thrown away rather than repaired. The answer in those cases becomes "To fix that cable you need to do X and Y and Z and it will take you 2 hours, so it isn't gene... (more) |

While I am (obviosuly) a "real name" type of person, there are definitely situations where using a pseudonym makes sense.

If you think the *answer* is "No!" then post such an answer. But even if you think the answer should be "No!", the *question* is great.

Wouldn't there be a *slight* advantage in a high-power application? If you have a lot of power == a lot of heat dissipation, then I think (but please explain if I'm wrong) that the parallel resistors would have a slight advantage, though if everything is run within specified limits then it shouldn't ...

I agree with almost all the points. But I do think some of the language is a bit inappropriate for something that may one day be more than just a random Answer but ideally part of FAQs (or similar).

A: How come the registers in a micro are application specific? While the terminology is similar to that of microcontrollers, and of CPUs in general, the "register" term here is specific to energy meters. Essentially, this board is a very basic version of a smart electric meter. The "register" term has been used for many years in Modbus (which is used for all sor... (more) |

One user might have the start of a great paper but simply not have the math or physics or whatever background to really flesh it out properly.

A lot has to do with collaboration. There are (arguably) three types of "bad" papers: 1 - "junk" - spam, intentionally misleading, etc. - those should get closed/moderated away just as with regular questions; 2 - not appropriate for a "paper level" post - these would (I hope) be rare - someone who ta...

*Self-answered questions is really a hack to use Q&A to write a paper.* Actually, I think self-answered questions take 3 forms - "paper" (as noted), "personal experience and want to let everyone know how I solved the problem" (quite common in some SE sites) and (what I expected): Examples of typical/...

I see the issues. At the same time, I think some of the "seed Q&A" already posted are almost at the level of scholarly articles, and left as ordinary Q&A they will get lost in the shuffle because *people looking for quick answers don't search very effectively and related articles are nearly as likely...

cost. **Can vendors change? Absolutely!** I have numerous examples, based on personal experience, over the years in both directions (good to bad and bad to good).

One of the ways to ensure an item is suitable (whether an electronic component in this case, or anything else) is to buy from an *appropriate* vendor.

Thanks for the explanation. I think the problem may come from the unintended ambiguity of "electronic and electric power" which can mean *to the uninformed*:
1 - *(electronic) and (electric power)*
or
2 - *(electronic and electric) power*
The simplest way to fix this might be to swap it to:
