Physics - E&M: Ch 40.1 Current & Resistance Understood (6 of 17) What is Resistivity? HD

Visit http://ilectureonline.com for more math and science lectures! In this video I will explain that resistivity is the property of a material that causes it to oppose a current. It depends on: 1) force/energy requied to remove an electron from an atom, 2) the mean free path of the electrons, 3) the fermi velocity and fermi energy.
