In the past a common appliance was to use a choke as part of an LC filter in a linear DC power supply, typically for tube amplifiers (where high voltage and low current was needed). There's where I've seen the term choke used the most. The difference to other inductors in this appliance is typically that the choke is built like a small transformer with very large inductance (up to tens of henrys), small current and most important, an air gap in the core to prevent saturation from the DC current. The size of the air gap can be calculated for the specific DC current that is needed. Without an air gap, the inductance will fall dramatically at higher loads. Such chokes can still be successfully used in linear power supplies, if the current demand is within the choke spec. For instance Hammond, Edcor, Lundahl and other transformer manufacturers have DC chokes in their sortiment.

From what i understand a choke is meant to handle power, like a power supply and alike.
And an inductor is the general term that is used everywhere and sometimes interchangeably with choke.
Personally i don't use the word "choke", i use the word "inductor" purely because i like it better.  :)
A choke is an inductor but an inductor is not necessarily a choke i think.

Also what about potentiometers vs rheostats?
Regarding the condenser and capacitor question, i've only heard the word "condenser" used in the context of old tube amps because it's (IIRC) the old word for capacitor.

Yes, it's the old word for capacitor. In Europe, variations of the Latin word "condensator" seems to be used in most languages (kondensator/condensatore/condensateur/kondensaattori etc.).

Well in my language it is "kondenzator" for a device and it has "kapacitet". So condenser for a device and capacity for the size of it's, well, capacity...
We use "zavojnica" (coil) and "induktivitet" for inductance value. Choke ("prigušnica") is used in context of usage, i.e. a functional explanation for a coil used for a use in a circuit, not for a component type per se.

We call voltage a "električni napon" ("electric tension")..
Electric potential is called a "potencijal", potential...
Current is called a "struja" which actually is a current.

I translate it to English when speaking English, but in my language it is not an "old" word but a very current one. I believe in German also... So we who don't speak English as a first language sometime slip up and use "Englified" version form our native language..

It does not matter most of the time, because it is usually understood anyways..

Same in my language (kondensatorius), but i forgot to mention that i was talking about the English language.
