--- Quote from: SiliconWizard on November 27, 2023, 10:04:54 pm --- --- Quote from: mawyatt on November 27, 2023, 03:26:07 pm ---So why don't we call a meter that measures capacitance a Farad Meter (or uFarad meter), or a meter that measures inductance a Henry Meter (or uHenry meter)? We also call a meter that measures power a Watt meter??? --- End quote --- We have LCR meters. The reason is that measuring pure capacitance (or inductance) is in practice of very little use, apart from quick checks, that many general-purpose DMMs embed. So that doesn't warrant a dedicated device. Same for measuring "power". There's more to it than just a value in W, so there's no point in making a dedicated device just measuring that (what power are you talking about anyway?) But there are devices such as "power analyzers", that can measure relevant parameters around the concept of power. Just lie for LCR meters - because a single raw value has no real practical significance, unless again you just need "quick checks", that again many general-purpose devices will offer. --- End quote --- We don't have volt meters either - they are typically multimeters and do at least resistance too. Of course, you can get just plain volt reading meters for niche use, but then I am fairly sure you can also get just plain capacitance meters if you have a niche for one. So why isn't that one a farad meter? Fewer syllables than 'capacitance' too (to head off other objections). I also don't think that capacitance depending on frequency and/or other stuff is relevant - the whole purpose of a capacitance meter would be to sort all that stuff out for you. That's why you pay the big bucks! |

Well, if you really feel there is a need for one, then build it and sell it and see how that goes. |

I find the OP's observation an intriguing one, and can formulate no logical or consistent answer. |
