Mounted Resistance Coils Length_55mm linking to additional holders in

linking to additional holders in series or parallel to extend bench-circuit voltage or capacity without soldering

the unit also runs as a motor on 6-8V DC for energy conversion demos

high-temperature grid flame for chemistry ashing

this student voltaic cell pairs metal electrodes with a porous cup separator and ships with an experiment guide for measuring cell voltage and potentials

Mounted Resistance Coils Length_55mm linking to additional holders inUsed to compare resistance against gauge, length, and material, this mounted board carries five labeled wire coils 22 and 28 gauge copper at 10m and 20m, plus a 22 gauge copper nickel.
