Rotary Potentiometers and Rheostats are two commonly used components in electrical engineering. They both act as variable resistors; however, they have different structures and principles of operation.

A rotary potentiometer, also known as a variable resistor or a rheostat, is an electrical component with three wire connections. It works by using a resistor that is positioned between the two end terminals, and the resistance can be adjusted by turning the knob. As the knob is turned, the resistance is changed and the output voltage is regulated accordingly. This type of variable resistor is used in various applications, including controlling the speed of motors, amplifying or attenuating signals, and adjusting the brightness of a display.

A rheostat, on the other hand, is a two-terminal device. It is composed of a wire winding with a sliding tap point along its length, and the resistance of the device can be adjusted by moving the tap point. Rheostats are primarily used for controlling the current in circuits, such as in motor speed control and in electrical heating elements.

The P16SNP104MAB15 is an example of a rotary potentiometer. It is an adjustable 20-turn potentiometer with a knob and three terminals. The output voltage is regulated by turning the knob and the position of the knob can be seen through a small window in the body. It is suitable for use in AC and DC circuits and is capable of withstanding a maximum power of 10 watts. The P16SNP104MAB15 is most commonly used in lighting applications, audio volume control, motor speed control, and industrial instrumentation.

The working principle of the P16SNP104MAB15 is quite simple. When the knob is rotated, the mechanical movement is translated into electrical signals which result in a change in resistance and output voltage. This change in resistance is defined by Ohm\'s Law and can be calculated by multiplying the resistance value by the current flowing through the device. The output voltage can then be determined by using the formula V = IR (where V is voltage, I is current, and R is resistance).

In summary, the P16SNP104MAB15 is an adjustable 20-turn potentiometer. Its main application fields include lighting, audio control, motor control, and industrial instrumentation. It works by converting the mechanical movement of the knob into electrical signals and regulating the output voltage accordingly. By using Ohm\'s and V = IR formulas, the resultant resistance and output voltage can be determined.
