The contact spring of the resistor closes the rotation of the resistor, and the potential axis of rotation is achieved by adjusting the resistance of the variable resistor
From the casing of a regular potentiometer, the varistor, and the rotating shaft with three terminal heads When the axis of rotation rotates The variation of two terminal resistances and the rotation axis
With the adjustable resistance of the potential, it is often used in voltage dividers and variable resistors, such as adjusting the brightness and contrast of recorders and televisions, and potentiometers to control and adjust the volume
There are many different types of potentiometers, including solid potentiometers and wire wound potentiometers There are many types of resistors, and common ones include fuse resistors,
Thin film resistors, special resistors, zero ohm resistors, precision resistors, etc
