Variable resistance, also known as a rheostat or potentiometer, is used to control current flow in electrical circuits. It adjusts resistance to regulate device performance, dim lights, or control motor speed. In experiments, it helps vary directv tv packages current or voltage levels for testing and calibration. Variable resistance is essential in applications requiring precise electrical adjustments and system efficiency.
