  2. A variable resistor is an electronic component that can adjust the electrical resistance value on demand123. It is used in electronic circuits to adjust circuit resistance to control voltage or current of that circuit or part of that circuit1. When the resistance of the variable resistor is varied, the electric current flowing through it will increase or decrease2. As the resistance increases in the variable resistor, the current through the circuit decreases and vice versa3. They can also be used to control the voltage across devices in a circuit3.

    The variable resistor is a resistor that controls (increase or decrease) the flow of electric current when we vary or change its resistance. In other words, when we vary the resistance of the variable resistor, the electric current flowing through it will increase or decrease.

    A variable resistor is the type of resistor which changes the flow of current in a controlled manner by offering a wide range of resistances. As the resistance increases in the variable resistor the current through the circuit decreases and vice versa. They can also be used to control the voltage across devices in a circuit too.

    How do you change the resistance of a variable resistor?
    The resistance of a variable resistor can be changed between zero to a certain maximum value with its third terminal. When the circuit diagram of the variable resistor in Figure 4 is carefully examined, you can see constant resistance exist between the terminals 1 and 3. Terminal 2 (in the middle) is the only terminal which has the ability to move.

    What is a variable resistor?
    A variable resistor is defined as a resistor whose value of electrical resistance can be changed on demand. It is a common component in electronic circuits that allows the adjustment of current or voltage according to Ohm’s Law. A variable resistor works by changing the length of its resistive track.

    What is a preset variable resistor?
    Preset variable resistors, wired as rheostats, are used in circuits to perform tuning or calibration. A digital variable resistor is a type of variable resistor where the change of resistance is not performed by mechanical movement but by electronic signals.

    What are the different types of variable resistors?
    There are different types of variable resistors available in the market, depending on the material and shape of the resistive track, the method of adjustment, and the range and linearity of resistance. The most common materials used for the resistive track are carbon, cermet (a mixture of ceramic and metal), and wire wound.
