with purchasing a new phone when Potentiometers are used to describe the language. This time to describe the need for a potentiometer of a few key points must be clear. 1: Model, (double-or single-joint) (with switch or not) the size or itinerary Procurement of a potentiometer , it is first necessary to understand the models or types of potentiometers. This will have the following a general direction. This is a first look at it or dial potentiometers or rotary potentiometers potentiometer sliding straight, or just to fine-tune resistance. Determined, to determine whether a single dial potentiometer or double-linked ones? How much slip you trip. . . . . Only make sure that these have a general pattern. Moreover, the factors that most affect the price. 2: Resistance and linear demands. Identified after the appearance of potentiometers, and then we should know the value of the potentiometer is the amount of deviation of resistance to accept what is? What is the linear resistance and so on. For example: B10K, signs that this potential resistance is 10K, linear for B.
