AC Electrical Circuit Analysis: Impedance

preview_player
Показать описание
In this video we introduce the concept of impedance. In general, impedance, Z, is a combination of resistance and reactance. Resistance can be thought of as a special case of the general concept of impedance, namely that of a vector with an angle of 0 degrees. Likewise, reactance has an angle of either +90 or -90 degrees, while impedance can have an angle anywhere in-between.

Good point, I’d read 628jΩ as “628 jiggaOhms”

Love these videos. I didnt get to study AC circuits in college, so its nice to be learning it now. Im also following along with your books

Brilliant, it's all becoming clearer and my Maths is improving. You draw the Inductor reactance/frequency graph as a straight line. That doesn't feel right, is it a good estimate or actually the case?
Many thanks, in advance. I'm really enjoying my morning brain workouts with you.
