Resistivity

Mr. Anderson explains resistivity, a property of materials that opposes electric charge flow. He demonstrates this using examples of gold, glass, and silicon, highlighting their different resistivity levels. The video distinguishes resistivity from resistance, explaining how factors like material structure and temperature affect resistivity. It also covers how to measure resistivity accurately, emphasizing the importance of using precise tools and considering material dimensions.
