Difference between magnetic field rheostat and potentiometer

Difference between magnetic field rheostat and potentiometer

Potentiometer is a kind of resistance that can be changed by mechanical adjustment (such as rotation, sliding, etc.), that is, variable resistor. It's the same. It's just different. It has three terminals. It changes the resistance value of variable output terminal to one end by changing the scribing position

Is sliding rheostat a potentiometer sensor?
RT

If the sliding rheostat is not connected with other physical quantities but only adjusted manually, it is only a manual operator instead of a sensor. Only when it is controlled by a physical quantity (such as mechanical displacement) can it be regarded as a sensor

In general, when the sliding rheostat is connected to the circuit, only the upper two terminals will make the resistance () and only the lower two terminals will make the resistance ()

In general, when the sliding rheostat is connected to the circuit, only the upper two terminals will make the resistance (short circuit), and only the lower two terminals will make the resistance (constant, constant, maximum)

The two wires are respectively connected to the two terminals on the rheostat. The current represents the number, the voltage represents the number, and the resistance is?

What rheostat are you connecting to
If it's a sliding rheostat
The above two terminals are metal conductors,
Therefore, the current flow is the maximum value
The voltage representation is 0
The resistance is 0
