Apparatus for Studying the Dependence of Electrical Resistance
Product Code : JL-GLE-11225
The Apparatus for Studying the Dependence of Electrical Resistance, SKU JL-GLE-11225, is a JaincoLab set for finding out what the resistance of a wire depends on. A 2-14 V AC/DC supply rated at 6 A drives current through test wires of different thickness (24 and 30 SWG) and material (copper and iron), while digital meters record current and voltage, so students can calculate resistance with R = V/I.
