Resistivity

Описание: 017 - Resistivity

In this video Paul Andersen explains how the resistivity of a material opposes the flow of charge. Conductors (like metal) will have a low resistivity and insulators will have a high resistivity. Semiconductors will have a moderate resistivity. Since the resistivity is determined by the atomic and molecular structure it is affected by changes in temperature.
