What caused the shift from calling things like rheostats and condensers to resistors and capacitors, or the move from cycles to Hertz?
It seemed to just pop up out of nowhere, seeing as the previous terms seemed fine, and are in use for some things today (like rheostat brakes, or condenser microphones).
What kind of amp uses a full farad of capacitance?
The ones I see tend to be a few thousand microfarads, maybe 20-40k for high end stuff. OTOH sometimes you see innoculous looking supercaps for storing settings; I’ve got dome out of an old Technics tuner that are like 3F… at 3v. Not sure there’s enough oomph to do that damage even at 3F.
