Technical Specifications
| Specification | Value |
|---|---|
| Tube length | 10 in (250 mm) nominal |
| Resistance wire | Oxidised constantan (Eureka) |
| Core | High-insulation vitrified ceramic tube |
| Winding | Side-by-side, uniform |

How It Is Used
The slider is moved along the tube to change the length of wire in circuit. In rheostat mode it sets the current for experiments such as Ohm’s law; in potentiometer (divider) mode the three sockets give an adjustable output voltage from a fixed supply.
