Conductors vs. Insulators: A Quantum Perspective

Electricity is created by electrons flowing through materials. Materials that allow electrons to travel through, like copper wires, are called conductors, whereas materials that inhibit electron flow, like rubber, are called insulators. However, the models behind our understanding have been incomplete. To understand which materials permit electron movement, scientists have investigated the patterns of electron motion in materials. Electrons do not behave like macroscopic objects. … Continue reading Conductors vs. Insulators: A Quantum Perspective
