AC Electrical Circuit Analysis: Series RLC Circuits

[@aerofart]

Excellent explanation of how to determine operating values for an RL series circuit. This is the first time in my life I am able to understand this stuff and put it to use in my beloved hobby. Thank you Professor! You’re a treasure!

Would be really nice to explain how you get the answers

I guess ihave forgot things over the years. What is j?

[@ElectronicswithProfessorFiore]

j is also called i (in math class, but we call it j because we already use i for current). It is the square root of -1, and is used to express the vector nature of the electrical signal (i.e., magnitude and phase). Can't do much in AC without using j.

@@ElectronicswithProfessorFiore OK, I am used to i.

[@faranocks]

where is the c?

This video starts with a more simple circuit using just R and L. Toward the end of the video I discuss how to handle the addition of a capacitor, C. For more detail, see the next video in this playlist, Series RLC Simulation.
