Potentiometer structure?
Potentiometer structure:
A potentiometer is actually a variable resistor, but it is seldom used when a variable resistor is used.
The potentiometer has three joints, in the two end with a certain potential difference, different potential sliding contact is in a different position, can cooperate with other components of various circuit, this is its main purpose.
There are different resistance and power, such as carbon film and wire winding structure.
