0148 30 32/33 0

Reproduces Ewald von Kleist's 1745 charge-storage device with concentric metal cups around a plastic dielectric

this metal-framed bench demonstration board uses variable resistors and switchable inputs to show how a meter measures V

sized for measuring direction and field strength on the lab bench

Extending up to 65 feet from a 20cm closed height on the included wooden stand
