L27 - Current Density, Conductivity, and Resistance#
ECE 343 · Spring 2027
Current Density, Conductivity, and Resistance
Current through a surface, Ohm’s law in point form, and what makes a good conductor.
Lesson 27 · Module 3: Magnetostatics · Maj Ellis · Dr. Neil Rogers
Learning Objectives
- I can calculate the total current through a surface area given a current distribution.
- I can use Ohm's Law for electromagnetics to calculate the relationship between a current distribution and an electric field.
- I can articulate and identify what makes a material a good conductor and how conductivity relates to resistance.
Spring 2025 Slides
These are last year’s Beamer slides, posted as they were taught while this lesson is converted to the new format. The fill-in handout, where there is one, is the copy to print and bring to class.
Reading
Ellingson, Electromagnetics, Vol. 1, Chapter 6.
Under Construction
This lesson is being converted to the new course format. The objectives and reading above are current; the notes, slides, and practice problems will replace the Spring 2025 material as they are finished.
