I would love to see a series: This Is What Electricity Looks Like to Me wherein you go through different components and talk about what the operating parameters are, and what different voltages, amperages, etc etc mean for that component.
I mean, you could have a series that explores and details the basics - ie, what is a resistor, capacitor, etc - and what they are used for, how they work, etc.
But what you are terming "operating parameters" are specific for each part per manufacturer. Now - a carbon-film resistor made by just about any manufacturer is going to be about the same from one to the other, as it's a basic technology. Even so, certain parameters might be different (ie - how much does the resistance change with temperature and humidity might vary between manufacturers). Also, none of that applies if we are talking about wire-wound, or some other kind of resistor (and different manufacturers).
Extrapolate this out to any other passive component, and you'll see the same thing (heck, just capacitors would overwhelm the idea). Get into simple actives (transistors, diodes, leds, etc) - and the amount of variation increases a magnitude, maybe more.
Then drop into other components - integrated circuits, electric motors, light bulbs - heck, even simple wire; you couldn't cover it all.
You'd know this, though, if you had any experience with electronics - which I suppose you don't, or you have little of it - otherwise you wouldn't be asking about such a youtube series.
Instead, you should start with the basics - and for that, you're going to need to read some books (the best would be Horowitz's "Art of Electronics" and Grob's "Basic Electronics"). While it might be possible to condense some of those books into a video series, it won't be a small video series (and if you want honest and in-depth explanations - such a series would not be the most exciting to watch).

but it sounds like you are looking for content that explains line by line what every parameter means for that component. I definitely understand why you'd be curious about that stuff (I definitely was) but after years of working in the field I came to learn that most of the parameters in a datasheet aren't actually useful or relevant to most designs. For example when picking a MOSFET the datasheet might have 40 lines worth of parameters, but only 5 of them are of actual interest to a designer in 99% of cases. So that's why I chose to produce content that directs the viewer's attention to the most important stuff rather than overwhelming them with edge case scenarios.
It is a gorgeous piece from the early 1900s and shows the craftsmanship that went into these earlier devices.
I appreciate you sharing this information.
Usually, potentiometers utilize a carbon-style track for the wiper; a few used a fine "wound wire" on a form for the wiper instead (they tend to handle higher power).
If it is a potentiometer - it will have 3 connections - one to each side of the main resistance element, and a third to the movable wiper. It might be a rotary style, or it might be a linear sliding style.
If it only has two connections - one to the sliding piece, and one to an end of the coil - then in that configuration it would be considered a rheostat (a potentiometer acts as a variable voltage divider, whereas a rheostat acts as a variable resistor/current limiter). If the coil is made of fairly substantial wire - then it was meant for power-controlling usage (if it is a potentiometer or a rheostat - usually a potentiometer can be used like a rheostat, but the opposite isn't possible with modifying the rheostat).
It is also possible it could be a "tunable coil" - similar to what was used in early crystal radio sets; such a device is not a potentiometer or a rheostat, and shouldn't be used or confused as one.
Huh?

That was done with a google search of "100k log potentiometer"...
Now - maybe you're in a different country or such where it's more difficult to get parts?
My introduction to the humble potentiometer was when my father (in the mid-1970s) became the first man in our street to have (home-made) variable-speed windscreen wipers in his car. He would have loved this book!
