AC Theory: Strange Currents in a Fluorescent Lamp Explained

[@AlanLumsden]

You're a good teacher Joe, don't let anyone tell you otherwise! 👍

[@JoeRobinsonTraining]

Thanks Alan, I really appreciate that. Stay tuned for more!

Thanks Joe. This video sort of "completes the circuit" of the mystery of the fluorescent lamp. What I need to do now is go back to the beginning of the series and watch them all again and I'm sure it will all make better sense. Looking forward to the Power Factor videos.

Still my favourite demonstration. I’ve built and regularly use the same rig with my students. It’s a fantastic resource learners understand.

[@brightspark263]

Wow absolutely brilliant Joe, everything is explained so easily. Really looking forward to the Power Factor videos.

[@JoeRobinsonTraining]

Thanks Chris, I hope I can explain stuff in an understandable way when we get to power factor.

[@deniscotter525]

Many tradespeople who didn't study trigonometry in depth, for that reason struggle to understand AC theory, your videos are excellent help in explaining the abstract of electrical engineering. Thanks 👍

[@markrowland5393]

Excellent. You explain this very clearly, thank you.

[@mohamedabdelmonem6468]

Outstanding explanation . organized, simplified and deep. Thanks

[@JoeRobinsonTraining]

Thank you kindly! 😃

[@charliedelacruz8555]

Good application for power factor correction....

[@daviddeleon292]

Thanks you for the videos. I never thought I would be able to understand these concepts but you are really helping me out.

[@JoeRobinsonTraining]

Ah, thanks for commenting, it's good to know they're helping. Keep up the good work David 👍

Hi Joe. Your videos are brilliant and your such a good clear and detailed speaker. Theres just one thing though. The introductory music is horrible. Lol please change it haha. I follow all your videos. Some tutors speak too fast and even though we can stop and pause/rewind ect, it's nice that you give us time to digest it as you speak. Cant emphasise enough how good a teacher you are. Wish you were my tutor .

[@JoeRobinsonTraining]

😂 Thanks for the kind words, maybe it is time for a refresh. 👍

[@ellisrolfe7331]

Well i was struggling a lot getting my head around this ! and light bulb moment just happened ! thank you very much !!!!!!!

[@kawdjer6463]

İ hope you keep doing videos. Things are explained very well and you are a very good teacher no doubt. All of your videos are very high quality. Even i do not have any electrical background, they made me curious as i watch these videos, and i keep watching and learning more. Thanks.

You're welcome, there'll be more content on the way soon!

Hi Joe, thanks for the great videos on AC circuits. Would this essentially be Kirchhoff’s Current Law for AC circuits? And what I’m really struggling with is understanding how the vector addition of the currents makes sense in terms of the physical charge carriers moving around the circuit, as it seems very intuitive to understand that the total charge carriers going into a junction in DC circuits will be the same as the total charge carriers leaving, but how would this apply in an AC circuit?

[@JoeRobinsonTraining]

The key to understanding it is to recognise that the currents are waves and they're offset from each other, which is what we mean by out of phase. 😊

So with the current being out of phase, it looks like current is flowing in two different directions through the circuit at the same time. Can current do that or is the current trying to go two different directions but it can’t so you get the amount/direction of current that you show where the two parallel lines of the current intersect? Great job on the videos, learning a lot so thank you!

[@isacdaimary9908]

Thank you sir, Can you please name some good books regarding this topic

[@tedlahm5740]

Kindly explain the function of the capacitor (the starter) in the firing up of the lamp. Thank you.

[@bsdiceman]

Thank you!

[@JoeRobinsonTraining]

You're welcome!

[@michaelcostello6991]

Where is the capacitor. Does every fluorescent tube have one ?
