Amateur Extra Class Lesson 4.3, Part 2, Principles of Circuits, 11th Edition

Here’s Part 2 of your video introduction to Section 4.3, “Principles of Circuits,” from the ARRL Extra Class License Manual for Ham Radio. This section discusses resonance, Q (quality factor), Properties of components at RF and Microwave frequencies, and magnetic cores. NOTE: NOTE: Lester Wetherell points out a mistake: “In your video amateur extra lesson [4.3 Part 2], made a mistake saying 10 pF = 1 X 10^-12. Just thought you should know. WD4IFU Lester” Yes, it should be 10E-12, not 1E-12. Sorry for the mistake.
