Product Overview
Resistance Wire Board – Equal Length, Same Material, Varying Diameter
This investigation board is ideal for exploring how wire diameter affects electrical resistance, while holding material and length constant. It features 8 nickel-chromium wires of equal 60 cm length but different diameters, all mounted on a durable laminated board. Decimeter markings along each wire support accurate measurement and data collection.
Perfect for hands-on experiments in resistivity and Ohm’s Law, this apparatus helps students draw clear connections between physical properties and electrical behavior.
Board dimensions: 65 cm × 22 cm.
Includes instructions.
Often used alongside the Mixed Materials Resistance Wire Board for comparative studies.
