Electromagnetics | 7-3: Surface Current Density | Purdue University
Current isn't distributed evenly across all conductors - let Dr. Michael Melloch, Electrical and Computer Engineering Professor at Purdue University, explain the concept of surface current density to you. This video focuses on the relevance and calculation of surface current density, which is the current flowing through per unit area of a conductor. By using an example where the surface current density is 10 amps per meter and the conductor width is 5 meters, Dr. Melloch explains that a current of 50 amps is flowing through the surface. Understanding the surface current density can help determine the flow of current through different conductor sections, leading to accurate electrical systems analysis and modeling. It plays a crucial role in various areas like power transmission lines, electrical circuits, and electromagnetic devices.
