Single-Phase Rheostat, 1000Ω, Alternate Model Light & Optics_Color Tabletop analog DC ammeter measuring

Tabletop analog DC ammeter measuring 0-1A at 0

designed to receive real images projected by lenses and concave mirrors during focal-length and magnification experiments on the optical bench

Built on a step-up transformer with an electromagnetic shaker pulsing the primary winding

this 4mm-stackable safety lead carries up to 12A through nickel-plated split-hollow pins on both ends
