D)controlling current direction

Question

Quizplus · Accepted Answer

Variable resistors, such as rheostats or potentiometers, can adjust the flow of current in a circuit, which can in turn be used to adjust the intensity of light in applications like dimming lights. They do not store electrical charge, create electrical energy, or control the direction of current.
