In this article we study how potentiometers work and try to understand how to connect potentiometers in electronic circuits. How Potentiometers Work Potentiometers, or pots as these are called in short form are passive electronic devices which are basically just variable resistors, or resistors whose values can be altered from zero maximum within the given […]
