Happy New Year everyone!
today I was playing with an LCR tester, I often use it to check inductors and capacitors. This morning I had a "blue" 3590s multiturn potentiometer (wire wound) in my hand. I was testing the value in ohms, then curiosity made me set to measure C too, that is the capacity. I noticed that by rotating the potentiometer the capacitive value is inversely proportional to the value of R. That is, the more the resistance increases, the capacitance decreases. The question is: do all potentiometers have this variable capacity? Thank you.
