I want to apply your advice to the operation of the "Joule Thief" circuit. While I have built several Joule Thief models before, I have struggled to explain the underlying logic behind its operation.
@@stepbystepscience No. What I meant is did you have the solution for an example of RL circuit which have V=20u(t) - 40u(t-1) something like this. I don't understand what's the point of the u(t). I can solve for simple questions like V=5 or V=20 but when the V equation becomes complicated, then I cannot solve the question.😭😭
Nick Step The inductor still has a built in resistance value, there is No physical way around that. You would have to measure the inductors resistance with a meter and use that value in the equation for the resistance.
I had the same question but he just simplified the equation by multiplying the the top and the bottom by R to get L on the bottom by itself. It ends up being the same value. He briefly mentions it when he first introduces this equation in RC Circuits Part 6 of 8 starting around 3:00. I hope that helps.
Love you and your channel.
Thank you so much!
very good explanation. love your channel. thank you so much :)
You are very welcome, thanks for watching and commenting.
Thanks for the video. It’s pretty helpful.

There must be a good explanation of the joule thief on the internet.
God bless you
Thank you so much and best wishes to you
Very nice nd easy to understand
Excellent!
Did you make videos about the voltage which have the u(t) terms? The u(t) really bothers me as I don't know what it was.
Do mean like this:

If we have the same Circuit without the Resistor, can we use the same equations you use on questions 3 and 4 ??

The induced voltage across the inductor? that should be 20(1-exp(-t/T)) where T=L/R

how to know how big inductor i need to connect sir ? i mean i have 17V ac, and current is 9.1uA so how would i calculate inductor values sir ?
You need to know the frequency of the AC voltage, the series resistor to determine the inductance.
