The potentiometer is a device that was developed in the early days of electronics development. The word ‘ potentiometer ’ is the combination of potential difference and metering. What Is a Potentiometer ? The potentiometer is basically a long piece of uniform wire across which a standard cell is connected. In the actual design, the long wire is cut into several pieces, and it is placed side by side and connected at the ends with a thick metal strip. The current flowing through the wire can ...
