Rotary Potentiometers and Rheostats are two basic components of electronic circuits, working together to control the power or current flowing through the circuit. The Rotary Potentiometer, PTD901-2020K-B103, is a device used to control the potential electricity (voltage) passing through a circuit. It is composed of a resistive element, a rotor, and a wiper. The resistive element is a semiconductor, made of a ceramic disc that is printed with a resistive film. The rotary element holds the resistive element in place and is able to rotate, allowing the resistor film to be moved to a new point. The wiper is a spring-loaded arm that is connected to the resistive element and is used to control the resistance along its length, by pressing against the resistive element. In this manner, the wiper is able to create a variable resistance. The PTD901-2020K-B103 also features a 10 turn precision potentiometer.

The main application of the PTD901-2020K-B103 is to provide a linear adjustment to a circuit\'s voltage. In circuits, the resistance of the resistor is linear, according to the relationship between Ohm’s law (V=IR). This means that as the resistance is changed, the overall voltage of the circuit will change accordingly. The PTD901-2020K-B103 works by adjusting the resistance of the actual resistor, allowing the user to manage the voltage passed through the circuit. For example, when the resistance of the resistor is changed, the wattage applied to the resistor also changes. As the wattage is changed, the voltage of the circuit is adjusted according to Ohm’s law.

A rheostat, on the other hand, is a variable resistor which operates on the principle of resistance. It is used to control the current flowing through a circuit. The working principle of a rheostat is similar to a potentiometer, in that it is able to control the amount of current that passes through a circuit by changing the resistance of the resistor. The rheostat works by having two contacts with a resistive material, which is connected to the circuit. When the knob is turned, the resistive material slides up or down, increasing or decreasing the total resistance. This can be used to control the amount of current that passes through the circuit. The rheostat works in tandem with a potentiometer, in order to control the voltage and current in a circuit.

The PTD901-2020K-B103 is an excellent choice for any application where precise adjustment is needed. It is able to provide precise control over the voltage passing through a circuit. Its 10-turn precision allows for more efficiency and accuracy when adjusting the voltage. It allows the user to quickly and precisely adjust the voltage in order to get the desired effect. Additionally, its ability to be used in tandem with a rheostat makes this device the perfect choice for when precise control over current and voltage is needed. The PTD901-2020K-B103 is the perfect choice for any application that requires precise voltage regulation and control.
