Rotary Potentiometers, Rheostats, and the P170N2-QB20BR100K are all three components used to measure resistance, or the ability of a material to resist the movement of electrons. These components have similar uses, but they have different construction and different working principles.

A Rotary Potentiometer is a type of resistor with three terminals: a start terminal, an end terminal, and a wiper terminal. The wiper terminal connects a rotating slide brush, allowing you to adjust the resistance between the start and end terminals. The location of the wiper determines the resistance and can be used to measure the resistance in an electrical circuit. Rotary potentiometers are used in the audio industry, in volume and tone controls, for example.

A Rheostat is a single-turn resistor with two terminals, a start terminal, and an end terminal. It is used to regulate the amount of current flowing between the two terminals, thereby regulating the voltage of the circuit. Rheostats are usually used in larger loads, such as motors or lighting, to control the amount of energy they consume.

The P170N2-QB20BR100K is a special type of rotary potentiometer designed to be used in temperature measurement. It has a built-in thermistor and is used to measure the temperature of a particular device by adjusting the voltage according to the electrical resistance of the thermistor. It also allows for fine adjustments of the power output, making it useful for accurately adjusting temperature readings.

In conclusion, a rotary potentiometer, rheostat, and the P 170N2-QB20BR100K are all components used to measure resistance. While they have similar functions, their construction and working principles vary and they are used in different applications. The P170N2-QB20BR100K is specifically designed to measure temperature, whereas rotary potentiometers and rheostats are used to control current and/or voltage.
