A variable resistor is used in some dimmer switches and volume controls. A potentiometer is a three terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. Where r resistance v voltage i electric current.
Where r resistance v voltage i electric current.
Definition of variable resistor it is an electronic component. The further the electrons have to travel through the material the more. The dial you turn will move another piece of wire inside the resistor. The variable resistor is a resistor that controls increase or decrease the flow of electric current when we vary or change its resistance.
