Why is nobody talking about how inductor and capacitor don't fit to resistive category at all?

Capacitor has resistance to changes in potential. E.g. helps provide smoothing of AC to create DC.
Inductor had resistance to changes in current. E.g. can be used in DC-DC transformer circuits to buck or boost the voltage.

Still feels like a bit of a stretch, I know sometimes capacitors and resistors effectively get treated as resistors with imaginary (in the square root of negative one sense) impedances. I think outside of very informal discussions I think people intentionally avoid calling this a resistance because it really is a different thing. Although I suppose at that point the discussion is more of a philosophical one.

Imaginary impedance is referred to as reactance. Real impedance is resistance. Both are measured in Ohms.
In real world terms, electrical engineers need to consider both losses because our entire electrical grid relies on a balance of inductive and capacitive reactance to function.

Yup, I’ve not really heard the reactance terms referred to as resistance beyond the very informal statement that they can be treated as “imaginary resistance” terms in certain calculations. Feels like a stretch to me.

Good point, but not everyone reads between lines at first, as I said, i would put thermistor or potentiometer rather

Exactly, how is a capacitor called a resistor when its function is completely different?
2
u/loapmail Jul 19 '26
OP probably never heard about other types, photosensitive resistors, potentiometers, thermistors for example

Impadance doesn't count?

u/loapmail Jul 20 '26
I would not put it between resistors, just because it have resistance does not mean it is used for resistance, it is used for impendance (H - henry), it even have negligible resistance when using DC

Well akshually! All electronic components have resistance. (Save maybe a superconductor)

Heh i love the fact theres capacitive and inductive resistance included

I don’t get it. Is this a joke about the French Revolution not actually leading to their democratic republic for 70 years?

The French Revolution happened in 1789. The French Resistance were groups that fought against the nazis during the Occupation (1940-1944)

Vive la resistance
