Скачать или смотреть Potentiometer comparison | Variable resistor cheap vs expensive

Hi friends in this video i compair 3 different Potentiometers . multiple turn potentiometers are high Precision potentiometers are designed for control applications where accuracy and high-reliability is important. These devices are available in conductive plastic, wirewound or element types, and in various sizes. I'm comparing 3 kinds of Potentiometer

potentiometers

multiple type of Potentiometers
Common potentiometer values (multiples)
By far the most used value for potentiometers is 10 kΩ, but other very common values are 1 kΩ, 5 kΩ and 100 kΩ.
Dual-gang pot: Two potentiometer combined on the same shaft, enabling the parallel ...
Concentric pot: Dual potmeter, where the two potentiometers are individually adjusted ...
Multi-turn pot: Multiple rotations (mostly 5, 10 or 20), for increased precision.
