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.

The essential circuit of a voltage divider, also called a potential divider, is:
Thevenization of the divider circuit will help you see how it operates.
it is aa linear circuit that produces the output voltage from the fraction of its input. It is also known as potential divider.
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 voltage divider circuit is a network of two or more components in series, often resistors, between a potential difference. The voltage between the components will be somewhere between the potential difference across the whole network and so divides the total voltage into one or more intermediate voltages.
No, rheostats are not typically used with fluorescent lights. Fluorescent lights require a specific type of ballast to control the current and voltage, which is different from the functionality of a rheostat. Using a rheostat with fluorescent lights can lead to inefficient operation and potential damage to the lights.
A paper sheet or a piece of thread can be used as a thin divider.
Dividers are used to divide humans.
A rheostat is simply a variable resistor used to control current. It does not have a positive or a negative terminal.
