Printing potentiometer models on What is the meaning?

When we examine the potential, not difficult to find, the potential will be printed on, for example: B20K, A50K, C100K ..... this writing, these represent what the meaning of it?
Today, Granville electronic potentiometer on the printing of primary school asked quietly tell you that!
In fact, ABC represents the resistance change characteristic of the potentiometer, while the letter the latter figure represents the adjustment potentiometer resistance range.
Oh this explanation is a bit too official language, that we explain in detail under
Take to illustrate B20K, B20K potentiometers, the letter B represents the resistance variation characteristic line B, is equal to 20,000 ohms 20K, then B20K indicates that B is a linear potentiometer, the resistance adjusting potentiometer 20K.
Immediately understand, there are wood?
Potentiometer divided by the change in resistance characteristics A, B, C three types, below, give you an analysis under three liters Electronic change characteristic features:
A type is exponential, exponential (inverse logarithmic) potentiometer at the start of the rotation, the resistance varies greatly. While in the corner closer to the end of the maximum resistance, resistance change is smaller. (Reverse logarithmic) potentiometer, the resistance according to the angle of rotation according to exponential changes exponentially, this type of potentiometer is used in which the instrument, but also for the tone control circuit, a conductive material such potentiometer resistor on distribution not uniform, at the beginning of rotation, a large change in resistance; rotation angle increases, the resistance change is small. Rotation angle logarithmic change in the resistance of the potentiometer. Therefore, this potential is applied to the audio circuit tone control circuit.
Type B is linear: a conductive material which resistor is uniformly distributed, the resistance per unit length is substantially equal to the angle of rotation changes potentiometer resistance value of a linear relationship, and more for the partial pressure; resistance even change according to the angle of rotation suitable for partial pressure, and other aspects of regulation monotonous. General linear potentiometer used more is this.
C type is logarithmic, logarithmic potentiometer at the start of the rotation, turn a small change in resistance value, and in the corner closer to the end of the maximum resistance, the greater the resistance change. Resistance by the rotation angle by exponential change, a conductive material such potentiometer resistor on the uneven distribution of the beginning of the rotation, the resistance change is small; when the rotation angle increases, the change in resistance is large.
Today l Electronic tell you these little knowledge there is no help to you understand simple potentiometer characterized it if you want to know more products can be registered or Granville Electronics official website:? Http: //m.888336.cn view
