Electronic Basics #37: What is Impedance? (AC Resistance)
video description
Also, can you please explain what's going on in an inductor when we turn on the current? On this graphic( shorturl. at/wBHP4 ) it seems that current is zero for 1/4 of period while voltage(and emf of inductance) are increasing. But how can emf of inductance increase if current is not changing? Or is it changing but by a very small amount?

How about if electricity was A-line made of a certain number of curves And those curves came back also so there is 2 directions of curves that stretched out through say a wire, you would have the same number of curves but by stretching them out they would get flatter and flatter which would represent less resistance which would mean you have to much energy coming back to the source or am I way off?

Thanks for the amazing content.
As you have measured the total current of a series resistor with capacitor. so I can calculate the voltage drop across resistor by simple Ohms law but what if I want to measure the voltage drop across the capacitor for some calculations then how to do it.
kindly help

Hi Scott, I have been watching a lot of your videos on theory of electronics and I have learnt a great deal from you. Now my question, there are so many books out there on electronics but what one book would you own if you could only choose one? Keep up the good work Scott

Why is reactance put into the imaginary number line? How was it known to use the complex number system to determine Impedance in the first place?

It's funny how on YouTube alone you can learn everything you need to be an electrical engineer. At least I don't pay for it.

starting to make sense, depends on frequency, ac resistance. pieces falling together slowly. =) yeah, watch this 1 more time.
