By using a Variac Transformer
A variac is a transformer device that controls the output of AC line voltage to an electrical or electronic device. The variac is available in different sizes to suit ones needs.
single phase variac can give 0-270 voltage in ac forms. So it is used to know the voltage in any circuit.
A single phase variac is used to adjust the output voltage in a circuit. It is often used for testing equipment, controlling motor speed, or regulating the output of power supplies. The variac can provide a variable AC voltage to the circuit, allowing for precise adjustments as needed.
A J4 variac is an electronics term. This term refers to the variable amount of wattage in the electric field.
In the electronics field, a J4 variac is a type of electric energy transfer. It involves the variance of the electric energy.

These devices could, in theory, be interchangeable. Variac is a (typically single coiled) variable transformer, whereas rheostat is a variable resistor. Although they may look just the same, they differ in one aspect - wire resistance. It should be as low as possible for variac, but it can differ on rheostats. So-you can use wire rheostat as a low efficiency variac and you can use wire variac as ridiculously huge rheostat, resistive range of which serves no practical purpose.
