Best descriptions I have found on the Tinternet about this subject by a very long way. A simple subject to understand with the right teacher. A very hard one to understand with the wrong one. Thank you so much for making this easy to follow. Great pace, great info and not daunting with yourself at all.
And the series rolls on. Joe Robinson training features highly on my CPD log. It's always great to see new ways of delivering a subject and your explanations are great for the learners to follow up with in support of their learning.
Yes I'd never done this before, one of the EAL questions asks about it so I thought I'd do it for real. Deeply fascinating how much you can calculate just from the figures in this video.
Thanks Alan, deeply fascinating how we can deduce so much about the coil and the circuit from so little information. Stay tuned for next Sunday's exciting installment!
Really helpful, clear and informative videos. Your series of videos on electrical theory have been really interesting. Its been a long time since I was a college. You forget things over the years. Good to re visit it...
Thanks Joe. I've followed all your training videos, which for me have been great but inevitably lead to more questions! Is this Lenz's Law? You mention RMS values, will you be doing a video on that?
Lenz's Law explains where the inductive reactance comes from and I will definitely do a video on RMS, just mulling over the best way to explain it at the moment so stay tuned!
Thanks for the feedback, I've got a few videos that explain level 3 science, I'll put a playlist together and keep on updating it. Stay tuned for more!
It's crazy how I can study this stuff and search for months to learn something then I find that one person who just makes everyone e else seem like they are intentionally confusing to keep you stuck in a rut. I'm studying electrolysis and magnetic pulsing. This gives me a great understanding. However what's keeping the electricity from destroying your power suplies?
Grossly misleading lecture! The inductor is made of copper wire which has small resistance. This resistance is limiting current in DC circuit. If this coil has s bery few turns your voltage will cause huge current and burn the coil. With ac source infuctance will limit ac current to very small current and coil resistanvce resistance iscirelevant.
Steady on there chap, "grossly misleading" is a bit much! It demonstrates neatly how AC and DC circuits operate very differently when they are connected to coils. It's aimed at level 2 or 3 learners who struggle to understand this concept that's all.
a very boring basic "mystery"? this type of teachings produces engineers with stagnant knowledge for decades that keeps doing the same thing over and over again
So you don't think electrical learners need to understand the different effects that DC and AC have on different loads? Fundamental physics isn't stagnant it's established and acts as a foundation.
i think we need an upgrade to teachings about electricity a bit more advance for college students because this subject is already taught in high school. you see most engineers vlogging about tesla's wireless energy transfer, some of them are even professors and master electricians, keep doing the same thing over and over again. building kilovolts of wireless transmitters just to light up a single led. tesla would have been so disappointed to see them makng hs invention a toy for big guys.
@@JoeRobinsonTraining i think we have been stagnant for century when it comes to electricity and so we stuck to batteries and miles of cables amd wires. havent anyone in this world figure out teslas idea? we transmit megawatts of electromagnetic waves around the world for decades but still no one figured out how to harvest them back in megawatt scale or at least just a little bit of energy transmission loss. where did the law of conservation of energy applied if we can only get milliwatt out that megawatt of transmission?
Dear Joe, you have a talent for passing knowledge in the most basic and simplistic manner. You make mission impossible become possible. Thanks.

Superb teaser for the juicy stuff to come 👍 Nice 1 Joe 😊

Excellent video. Very clear and well explained.
Thanks Mark!

Good to know, thanks for the feedback, hope future videos are as helpful. Stay tuned!
Very good and clear explanation. Thank you!
Clear concise explanation. EXACLY what we all have come to expect from you. A thank you.
Ah, thanks very much Ted, that means a lot.
Many thanks sir.. You are doing a great work....This is very helpful to us.. I wish you to success your all works..
Thanks very much!
What an epic end of the video!👏🏻Absolute love it.Well done Joe!
Thanks very much! 😂
Thanks Joe

Ref RMS. If we divide the 15.5 volts by 0.707 we should get a number for peak voltage in an AC ckt.
True dat.
Hello Joe...
Please help me to understand transformer less power supply design for lightning LEDs... 🙏
6:20 Joe, does the presence of the secondary coil have any influence on current reading?
Not really in this instance, as there's nothing connected to the second coil. Great question though. 👍
Great videos any chance you can do a couple of videos on 2365 level 3 that would be great thanks
Thanks for the feedback, I've got a few videos that explain level 3 science, I'll put a playlist together and keep on updating it. Stay tuned for more!
If you could I'm going back to college in September so want to brush up and hit ground running
great video!! thank you very much!!
What frequency was at AC supply?
This video should be made with scope showinbg actual current waveforms in DC and AC circuit. Current multimeter hides the real effects.

Thank God, we now have a messiah who's going to save us all from stagnation. Dear all, meet Jedab, the man who will take us to the new age.
