Example include: adjusting lamp brightness, adjusting motor speed, and adjusting the rate of flow of charge into a capacitor in a timing circuit. Variable resistors (potentionmeter) This type of variable resistor with 3 contact (a potentionmeter) is usually used to control voltage. It can be used like this as a transduser converting position (angle of the control spindle) to an electrical signal.
