Product Overview
Resistance Wire Board – Equal Length, Mixed Materials, Same Diameter
This educational apparatus allows students to explore the impact of material type on electrical resistance while keeping wire length and diameter constant. The set includes 8 wires made from a variety of materials—Silver, Copper, Aluminum, Nichrome, Iron, Stainless Steel, and Constantan—all mounted on a durable laminated board. Each wire is 60 cm in length with decimeter markings for precise measurement.
Ideal for experiments on resistivity and material conductivity, this board helps students compare how different materials affect electrical resistance under identical conditions.
Board dimensions: 65 cm × 22 cm.
Includes instructions.
Often used in conjunction with the Resistance Wire Board – Equal Length, Same Material, Varying Diameter for side-by-side material and geometric comparisons.
