A variable resistor is another name for a rheostat.
Another name for variable resistance is potentiometer. It is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.
The hypothesis of a rheostat is that by changing the resistance in a circuit using the rheostat, the current flowing through the circuit can be varied, thus regulating the output of the circuit.
Yes, a potentiometer can be used as a rheostat by only using two of the three terminals. By connecting one end of the resistive element to the wiper terminal, you can adjust the resistance across the other two terminals to control the current flow like a rheostat.
A rheostat with a 15 ohm resistance is used in Melde's experiment to control the amount of current passing through the system. By adjusting the resistance of the rheostat, the frequency of vibration of the standing wave on the string can be varied. This allows for the different modes of vibration to be studied in the experiment.
The rheostat was invented by Sir Charles Wheatstone in the early 19th century. Wheatstone was a prominent English scientist and inventor who made significant contributions to the field of electrical engineering.

how to test a rheostat?
Rheostat is the name of an instrument used to vary electrical resistance.
It is lost in heating the resistive material of the rheostat.
The hypothesis of a rheostat is that by changing the resistance in a circuit using the rheostat, the current flowing through the circuit can be varied, thus regulating the output of the circuit.

A rheostat is the name given to a variable resistor when it is used to control current. When a variable resistor is used to control voltage, we call it a potentiometer.A rheostat is connected in series with a load, and two of its three terminals are used. A potentiometer is connected in parallel with the supply, and each of its three terminals are used.So the terms 'rheostat' and 'potentiometer' are the names given to describe the function of a variable resistor, not the variable resistor itself.

_____________ J| -_____/\/\/\/\_________+ | | | - + | |___i|i|___| E Well this is the circuit diagram , where r is the sliding jockey of the rheostat and a cell (E) is connected in parallel with the rheostat. By adjusting the jockey resistance of the rheostat can be altered which in turn would regulate the potential offered by the cell E to the main circuit. And thus a rheostat can be used as a potential divider.

A potentiometer and a rheostat are two different applications for a variable resistor.A potentiometer is a variable resistor, connected (using its three terminals) as a variable potential divider.A rheostat is a variable resistor, connected (using two of its three terminals) to adjust current.
