Rotary potentiometers, and rheostats are devices used to measure and control electrical current. While these devices appear quite similar, their operating principles and main uses differ significantly. The 3-1625931-8 is a type of rotary potentiometer.
A rotary potentiometer is constructed with a knurled shaft and fixed resistor. The component functions as a voltage divider. The position of the shaft is what determines the amount of current or voltage divider and the resistance value. Essentially, as the shaft is turned, the wiper moves along and the voltage that is being divided decreases or increases accordingly. This makes the rotary potentiometer ideal for measuring changes in voltage and/or current.
The 3-1625931-8 is an especially important component in the construction of breadboards and electronic toys. These devices use the control variable (which in this case is the position of the shaft of the rotary potentiometer) to adjust the amount of current in the circuit. In this way, builders of such breadboards or toys can control how much current is actually sent through a particular circuit.
Rheostats are also related to electrical current, except they differ significantly in the way they work. A rheostat is a variable resistor, which essentially changes the amount of resistance in a circuit. This allows the user to control the amount of current that passes through the circuit. As the resistance is changed, the amount of current passing through the circuit decreases or increases. Thus, rheostats are the perfect component for measuring and controlling overloads by limiting the amount of current passing through a circuit.
In conclusion, rotary potentiometers and rheostats serve two very different functions. While rotary potentiometers are great for measuring and controlling voltage and/or current, rheostats are perfect for limiting the amount of current passing through a circuit. The 3-1625931-8 is an especially useful type of rotary potentiometer that is frequently utilized in breadboards and electronic toys.
