Description

Day 3 of Linear Circuits.  Students are introduced to current sources.  It turns out, current sources only have one job.  That never changes, and as long as we remember that, they are pretty easy to work with.


The material covers all of the lecture material from a third lecture in a traditional, sophomore-level linear circuits class.

Who this course is for:

  • Beginner Engineering and Physics Students
