Copper Calorimeter, 100 x 75mm Entomology & Zoology_Dissection Ten-ohm 5W wire-wound fixed resistor

Ten-ohm 5W wire-wound fixed resistor in a self-contained ABS module with 4mm sockets

Used to compare two unknown resistances by null-deflection on a sliding-wire jockey

an electrophorus

each topped with a small handling knob and stored in a hardwood block for classroom balance coursework

sized so that students can charge an outer pail and watch the inner pails register zero charge during the classic ice-pail demonstration
