Why no Farad or Henry meter?

<< < (11/12) > >>

TimFox:
However, one does sometimes encounter a "Coulombmeter" to measure charge.
Many of the ones listed now are for estimating battery charge, but some are for sparks or surface charge.

Volts, amps and watts are all dynamic derived values. I wonder if that has a bearing, or if it's just coincidence that the group lend their names to instruments.

DavidAlfa:
I completely understood the first post, can't figure out how so many people struggled?

Yeah, it's interesting at least, You don't measure caps in "capacitances" (Please source a 25V 100uCapacitances capacitor!) neither coils in "inductances".
If those are called LCR meters (Or just capacitor/inductor meters when doing only one measurement type), then the rest should be voltage/intensity/resistance meters, not volt/amp/ohm meters.

And why is this called a flexometer?
It measures distance, not flexing, so it should be called meter/distance/length meter !  :D

CatalinaWOW:
I think the prior post referencing the time frame of the naming nails most of the reason.With a residuum coming from the size of the units.  Volts, Ohms and Amperes are quantities encountered commonly.  But a Farad capacitor was unimaginable until 20 or 30 years ago.  Henry inductors are not quite as outre, but neither is commonly encountered.

I think the references to parasitics is a red herring.  Many applications can neglect these in inductors and capacitors, and many applications care about parasitics in resistors and ripple, noise and other details in measurements of voltage and current.

Are you sure?

I think you are arse about face on that. The question is why there are no 'farad' meters or 'Henry' meters, not noting that we don't use voltage or intensity or flex meters.
