INSTRUCTIONAL APPARATUS TO DETERMINE THE LIGHT CONDUCTIVITY STRENGTH OF VARIOUS SUBSTANCES

摘要

Disclosed is an instructional apparatus used to determine the light conductivity strength of various substances by measure the brightness or dimness of a light bulb during testing. The testing comprises of exposing a substance to an open container that is exposed to open wires which are connected to the light bulb. The apparatus can be applied in experiments for physics and chemistry students but can also be applied for other purpose.
