Its a sign of resistor with a tilted arrow.
The symbol for a rheostat is a resistor with an arrow indicating a variable resistance that can be adjusted by a knob or slider. It is commonly used in electronic circuits to control the flow of current.
The JIC (Joint Industrial Council) symbol for a rheostat is represented by a rectangle with two terminals on one end and a wavy line indicating resistance or adjustable resistance within the rectangle. This symbol visually conveys the function of the rheostat as a variable resistor. It is often used in electrical diagrams to signify devices that control current flow by adjusting resistance.
how to test a rheostat?
A variable resistor is another name for a rheostat.
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.

_____________ 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.

To check a rheostat, start by ensuring the circuit is powered off for safety. Use a multimeter set to the resistance (ohms) setting, and connect the leads to the two terminals of the rheostat. Adjust the rheostat's knob or slider, and observe the multimeter reading; it should change smoothly as you adjust it. If the resistance does not change or shows an open circuit, the rheostat may be faulty.
