These resistors are also called potentiometers; they allow a level of monitoring over the resistance within a circuit. This gives them support over the other types of fixed resistors as per your needs. They are made up of a fixed resistive element. This is how to make changes in the resistance of a circuit, and it is usually controlled from outside.
The term potentiometers are used when a variable voltage is received at the wiper end, a fraction of the fixed potential throughout the track. It has to be a two-terminal device that carries different resistance throughout the two terminals.
The potentiometer has the resistance of the track constant the same as the wiper moves, and it has the potential to make changes to the wiper. A variable resistor can resist track changes such as the wiper moves and short circuit of the track resistance.
A variable resistor is a device that is not limited only to the flow of electric current but also controls the decrease and increase in the flow of electric current supply and is called a variable resistor. When we change the resistance of a variable resistor to a bigger resistance value, the electric current passing through the variable Resistor will decrease. Similarly, if we vary the resistance of the variable Resistor to a small resistance value, the electric current passing through the variable resistor will increase.
The most common use of this resistor is to control the volume on radio and TV. They can also contribute to and use as an integral part of light dimmer to indirectly affect light intensity. These are used to control a circuit's resistance. These devices range from zero to maximum resistance. Their circuit diagram shows a constant resistance between terminals 1 and 3, and one terminal (terminal 2) is moving. To change the resistance, you must use the other side of the circuit. This can be done by placing the moving terminal on the other side of the Resistor.
To change the resistance, you must adjust the two terminals. An adjustable resistor has a nominal resistance. Because it can be easily modified, its resistance will not exceed its nominal value. A variable resistor can be used for voltage regulation or variable resistance. The range of resistance it can reach is dependent on its use. This is why it is essential to ensure the limits of adjustable resistors before using them. If you don't know the proper value, you may have to experiment with a smaller or larger value.
