Description
The rheostat is a device made of resistance wire and insulating material, with a sliding contact and cast-metal end cheeks. It allows for the adjustment of electrical resistance in a circuit without interrupting the flow of current. It is commonly used to demonstrate the function of dimmer switches and motor speeds.
The rheostat is made from resistance wire wound on an insulating, heat-resistant tube. It is supported by cast-metal end cheeks and has a sliding contact. It allows you to adjust the electrical resistance of a circuit without intefering with the flow of current. It's used to demonstrate how dimmer switches and motor speeds work.
