Key Features
- Total resistance of 100 Ω.
- Carries up to 1.6 A.
- Oxidised constantan (Eureka) winding for stable resistance when warm.
- Spring-loaded slider on a chrome-plated brass rod.
- 3 colour-coded 4 mm binding posts, so it also works as a potential divider.

How It Is Used
Using one end terminal and the slider, the rheostat acts as a variable resistor to adjust the current in a circuit for Ohm’s law and similar experiments. Connected across a supply by both end terminals with the output taken from the slider, it becomes a potential divider giving a variable voltage.
