adjustable resistor definition
variable resistor. A rheostat. variable resistor - Computer Definition. An electronic component that is used to vary the amount of current that flows through a circuit. It works by sliding a wiper terminal across a resistive material, typically a thin film or chunk of carbon or a resistive wire made of nickel chromium or tungsten alloys. A potentiometer is a manually adjustable variable resistor with 3 terminals. Two terminals are connected to both ends of a resistive element, and the third terminal connects to a sliding contact, called a wiper, moving over the resistive element. Popular Terms. A device used in electrical current conduction to control the direction of the current flowing to a circuit by applying resistance. Resistors may be fixed or variable, both controlling the flow of current differently. Use 'resistor' in a Sentence. | adjustable resistor in French | adjustable resistor in Italian | adjustable resistor in Spanish | adjustable resistor in Dutch | adjustable resistor in Portuguese | adjustable resistor in German | adjustable resistor in Hebrew | adjustable resistor in Catalan | adjustable resistor in Swedish. variable resistor. 1  dimmer - a rheostat that varies the current through an electric light in order to control the level of illumination. 2  resistor, resistance - an electrical device that resists the flow of electrical current. rheostat - resistor for regulating current. variable resistor. dimmer - a rheostat that varies the current through an electric light in order to control the level of illumination. resistor, resistance - an electrical device that resists the flow of electrical current. contact arm, wiper arm, wiper - contact consisting of a conducting arm that rotates over a series of fixed contacts and comes to rest on an outlet. Potentiometer definition. A potentiometer is a manually adjustable, variable resistor with three terminals. Two terminals are connected to a resistive element, the third terminal is connected to an adjustable wiper. The position of the wiper determines the output voltage. Variable Resistor. 1  As the wiper is moved across the body of the device, the resistance increases between the wiper terminal and one end terminal and decreases between the wiper and the other end. 2  Potentiometers are variable resistors commonly used to control the volume on a radio or music system. - notes or overview about the adjustable resistor or variable resistor used as a trimmer resistor and the circuit symbol. Variable or adjustable resistors are often needed within electronic circuits to act as a preset control within the circuit. The variable resistor, is also widely referred to as a potentiometer as a result of its configuration. variable resistor. variable resistor.
