How to Identify Electrical Conductors and Insulators

Next Generation Science

This educational video provides a clear and practical introduction to electrical conductors and insulators. It begins by defining the core property that distinguishes these two categories: the ability to allow electricity to flow through a material. Through a series of clear demonstrations using a simple electrical circuit, the video tests various common household items—including aluminum foil, a rubber band, a metal screw, a quarter, and a plastic block—to determine their conductivity.
