Rheostats, or variable resistors, are used in electric circuits to provide variable resistance for applications like adjusting volume and controlling brightness. They allow for the adjustment of current flow by changing resistance.
Rheostats, also known as variable resistors, are devices used in electric circuits to provide variable resistance. They are commonly used in applications like adjusting volume in sound equipment, controlling the brightness of lights in dimmer switches, and regulating motor speeds. A rheostat allows for the adjustment of current flow in a circuit by changing its resistance.
