About This Product
A rheostat varies the current in a circuit by changing how much resistance wire is in the path. In the physics or electrical lab it is used to set and adjust current in practicals such as Ohm’s law and potential divider circuits, where the grooved former helps the wire shed heat. The Rheostat Groove Type (Wound with imported bare Wire) can be supplied on export terms to Philippines, Lesotho, Bhutan, Uzbekistan, United Kingdom and Georgia.
Frequently Asked Questions
What keeps the Rheostat Groove Type cool in use?
The wire is wound on a pipe with a deeply grooved outer surface, which leaves air channels for convection cooling.
How does the slider make contact with the wire?
Two copper brushes with a large contact area press on the Eureka resistance wire, giving smooth current control and very little wear.
