@#36396 Entirely reasonable. (more) |

Aren't battery capacities typically specified assuming some particular discharge rate (and to some specific charge state)? A battery capacity Ah rating might be accurate at 0.05 C but wildly inaccurate even at 0.2 C.
A UPS battery would seem to likely be discharged at a fairly high rate while in u... (more) |

* A rotational hard disk will typically draw ~10-15 W maximum; a SSD on the order of 1/10 of that
* A modern computer monitor can be expected to draw a few tens of watts while turned on; size and panel type influence this
* A USB hub will use negligible power unless it's USB-C PD and you're chargin... (more) |

You talk repeatedly about "batteries" in your question, and you even once mention a hypothetical "consumer" purchasing batteries, which leads me to believe that you're interested in answers relating to batteries for end-user use, more than you're interested in answers relating to cells intended to be...

@#8056 A "headset", as the term is often used, is nothing more and nothing less than an earpiece and a microphone somehow combined into one unit. If it lacks a microphone, it's simply a set of headphones. What kind of plug it has (if any; consider wireless units) is unrelated to that designation. (more) |

@#53509 I'm going out slightly on a limb and assuming that it's [for fun](https://electrical.codidact.com/comments/thread/6474). (more) |

Please use Mathjax to typeset equations in a readable manner. A seemingly handwritten (hand-drawn) and scanned image does not lend itself to being read easily. (more) |

A bandpass filter doesn't have a specific bandwidth. It has a bandwidth *at a given degree of attenuation*. Since the edges aren't infinitely sharp, you have to specify the attenuation at the limits of the desired passband. 2 Hz (centered at 10 kHz) at -3 dB is very different from, say, 2 Hz (centere...

@#54107 There is no such thing as square waves in the physical world. A "square" wave is just a number of superimposed sine waves. (more) |

Should it be possible to configure something like this on a per-category basis, or should it be an all-or-nothing deal across a community? (I suspect that the work involved in implementing this would be similar either way, which itself would seem to me to suggest that the former would be preferable.)... (more) |

For the sake of argument, suppose this is implemented as you describe. What should happen to existing downvotes once the functionality goes live? Should they be somehow grandfathered in as anonymous; publicly attributed to the user(s) who cast them under the assumption that votes, unlike reactions, w... (more) |

@#8176 Yes, even Wikipedia lists a few slightly different definitions; but if we have to pick one, I'd say IEC/ISO is probably a better choice than most other choices available, and it's certainly a lot better than coming up with something that applies only on Electrical Engineering Codidact.

I suspect that your *actual* problem isn't that you truly only want to know the internal resistance of the ammeter in question, but rather something else, and that you believe that knowing the internal resistance will tell you something about what you are *actually* trying to determine.
So what pr... (more) |

@dustytrash Even if you had access to a full and accurate schematic, that looks a whole lot like a multi-layer PCB to me, and it's definitely packed with surface-mount components including delicate ICs. Even if you had the knowledge, that's not something you "fix" with tools even most electronics ent... (more) |

I don't know how the Roomba charging circuitry is designed, but it's not at all unreasonable, particularly in consumer electronics, to not have direct DC connectivity between a charger's output side and a built-in battery. If it uses a lithium-based battery chemistry (a good guess in today's world, t... (more) |

@TonyStewart Maybe Morse code can be considered one such example, with variable-length symbols? It would probably be tricky to analyze as such, but I suppose technically it fits the definition... (more) |

@MonicaCellio That's odd; that must mean that multiple people retracted their votes between [Nov 28 23:34:07 UTC](https://web.archive.org/web/20201128233407/https://electrical.codidact.com/questions/279484) and whenever exactly Codidact was taken offline for the second time.

@MonicaCellio Votes are still missing. https://electrical.codidact.com/questions/279484 is one concrete example, but I wouldn't rule out the existence of other cases. I mentioned this at https://meta.codidact.com/a/279504/279560. (more) |

@ElliotAlderson At which point you get puzzled looks until you tell people that the DTMF value set is actually 0-9 plus \*, \#, A, B, C and D, which adds up nicely to 16 distinct values. (more) |

Regarding power supply replacement, I realize that this is *Electrical Engineering*, but I really think this answer should say something about AC vs DC supplies. (I suspect that AC-AC power supplies that actually change the frequency of the voltage would be too niche a case to cover in a general-purp... (more) |

Regarding the section on current rating: One comparison I've used at times, seemingly with good results, is that of the power grid. Whatever the rating of the fuses (40 A or more in 120V countries, 15-20 A in 240V countries, typical), most people recognize that just because the outlet *can* provide t... (more) |
