Adjustable power resistors are electrical components that are used to introduce electrical resistance into a current-carrying circuit. They are used to limit the flow of current, balance voltage, and regulate power levels. D75K100 is one of the most popular and commonly used adjustable power resistors available on the market. There are three main components to this resistor: two adjustable resistors and a slide switch.

The D75K100 is a type of resistor array that comes with two adjustable resistors (R1 and R2) arranged in a series-parallel configuration and a sliding switch (S1). The two adjustable resistors are connected in series at one end, and in parallel at the other. The sliding switch provides a fixed resistor (Fi) which can be used in place of either adjustable resistor. Thus, the total resistance of the resistor array can be adjusted by selecting the appropriate combination of the adjustable resistors and/or the fixed resistor.

This type of adjustable power resistor is primarily used to regulate the output voltage of a dc power supply. It is also used to adjust the current and voltage levels of a circuit. As the adjustable resistors are connected in series and parallel, they are able to provide resistance levels from 0 ohms to the full rated power of the unit. This makes the D75K100 suitable for a wide range of applications, such as in motor control circuits, switch-mode power supplies, and four-quadrant power supplies.

The working principle of the D75K100 is simple. When the voltage across either of the adjustable resistors is increased, the total resistance of the array decreases. Thus, more current is allowed to flow through the resistor, and the output voltage is decreased. Similarly, when the voltage across either of the adjustable resistors is decreased, the total resistance of the array increases, and less current is allowed to flow through the resistor, resulting in an increase in the output voltage.

The D75K100 is also capable of providing linear and/or non-linear resistance adjustment. By changing the type of resistor connected to the resistor array, it can be used to provide either linear or non-linear resistance adjustment. This feature makes the D75K100 an ideal choice for applications that require adjustments between a minimum and a maximum value.

Overall, the D75K100 is a versatile and reliable adjustable power resistor. It is capable of providing a wide range of currents and/or voltages for a wide range of applications. Furthermore, its simplicity of operation and resistance adjustability make it a popular choice for both electrical engineers and hobbyists alike.
