Advanced Laboratory and/or Lecture Demonstration Apparatus and also Low Cost

Apparatus Title: An Equipotential PCB

Abstract An inexpensive and versatile apparatus has been designed for measuring the equipotentials between a set of metallic electrodes. The apparatus is a low cost (less than $50) alternative to the electrolytic trough or the resistive paper apparatus currently in use. It can incorporate electrodes of any size, shape, or configuration.
