Mixed Materials Resistance Board
Show how different wires of the same diameter differ in conducting electricity
Supplier: Science First 6154596
Includes: Mounting board with silk-screened scale; eight wires of the same gauge but of different materials: silver, aluminum, copper, nicrome, iron, stainless steel, constantan; and detailed instructions with graphs
Description
Students can calculate the resistivity of the higher resistance wires and compare them with theoretical values. By graphing the resitivity, they can see the linear nature of resistance in wires.
- Convenient scale is silk-screened onto the mounting board for easy measurements
- Banana plugs on either end allow for easy connections
