Rotary potentiometers and rheostats are two electrical devices used for administering wattage to a circuit. They are very closely related, but serve slightly different purposes. The 3547S-1AA-103A application field and working principle serves as a good example of the differences between the two.

Rotary Potentiometers

A rotary potentiometer is a three-terminal variable resistor. It is composed of a resistive element and a contact wiper which sweeps across it. The third terminal is the connection between the contact wiper and ground. When the contact wiper rotates, it changes the resistance between the first and the third terminal. The resistance is inversely proportional to the position of the contact wiper. This device can therefore be used to control the voltage and current in a circuit.

In the case of 3547S-1AA-103A application field and working principle, this device is used to control four wattage levels in a circuit. It is composed of a ceramic element, and four wiper arms. As the wiper arms are rotated, they change the resistance between the wiper arms and the third terminal. By adjusting the position of the wiper arms, the resistance changes and the wattage in the circuit is modified accordingly.

Rheostats

Rheostats are two-terminal devices which are used to control the resistance in a circuit. They are composed of a resistive element and a contact wiper. As the wiper is rotated, it changes the resistance between its two terminals. This device is used to control the wattage in a circuit by adjusting the resistance between the two terminals.

The 3547S-1AA-103A application field and working principle uses a rheostat to control the four wattage levels in a circuit. This rheostat is composed of two resistive elements, which are connected in series. As the wiper is rotated, it changes the resistance between the terminals, and thus affects the wattage in the circuit. By adjusting the position of the wiper, the resistance can be changed and the wattage in the circuit can be modified accordingly.

Conclusion

In conclusion, rotary potentiometers and rheostats are two closely related electrical devices used to control the wattage in a circuit. While they both accomplish the same goal, they have slightly different operating principles. The 3547S-1AA-103A application field and working principle provides a good example of the differences between the two, with the rotary potentiometer controlling four different wattage levels, and the rheostat controlling one.
