20k Variable Resistor Potentiometer Volume Type

Variable Resistor Potentiometer Volum Type:

A variable resistor is the most significant component found in many electrical devices for controlling the tone, bass as well as volume. This is due to the fact that resistors can be connected together with the other components to form filters for the desired level. They can also be used in computer monitors for color or positioning as well as dimming or switching lamps. This is achieved through digital to analog andanalog to digitalcircuits; one additional advantage is that the knob can be turned instead of typing a value every time you want to change the tint or brightness.
