How to Calculate Inductive Reactance & Impedance for a Resistor & an Inductor connected in Series Q1
Вставка
- Опубліковано 6 сер 2024
- In this video we look at how to calculate resistance and impedance for a resistor and an inductor connected in series or what's known as an RL series circuit, which is a way of representing the behaviour of a coil. We also demonstrate how to draw an impedance triangle to scale, calculate current and voltages within the circuit and find the true power.
This video is designed to be used in conjunction with the worksheet accessible from the link below. Please attempt each question in turn and then watch the video, accessible by scanning the QR code in the worksheet to see a worked answer to the question:

This is an excellent series from start to finish. Have not seen a better, more concise presentation of the topic. Thanks for the time & effort spent putting these together.
The fact you drew the right triangle symbol is chef's kiss.
You know how we do! 😃
Thanks Joe. Six months ago this would have Greek to me but having worked my way through your AC Theory playlist I managed to get the answers to these questions on my own before I watched the video. I am absolutely chuffed, thanks to you!
Such a great comment, it's part of my goal to help people get to a position where they can answer questions like this with little to no previous knowledge. Stay tuned for more!
Thank you so much sir am grateful
I would just like to say, I have watched the ac playlist through to this point and managed to answer all of the questions in this video before you showed the calculation, and I am feeling pretty pleased with myself right now. This is down to the way that you have taught me on the way through. many thanks for putting this online....brilliant....
I absolutely love this kind of comment. It makes me so happy to know that it's helping people. 👍
This is really helping me to understand the concept and theory behind it. Thank you.
Brilliant teacher
So helpful, thank you. I sometimes feel overwhelmed by how much there is to learn. These videos help break it all down and really help my understanding
There is a lot to learn but don't feel overwhelmed, just take it a bit at a time and remember the exam won't be as bad as you think!
You are the best one i like to follow your videos.
It is so benefit for me and all followers.
Thanks very much, stay tuned for more!
Many thanks Joe be honest with you I start studying level 3 this year it was very tough course until I watched your videos and everything became easy.
God bless you and your family.
Glad it's helping! 😃
I pulled this up as a refresher since it’s been about 10 years since I had my EE course where this was covered this. I must say, I don’t remember it ever being taught to me in the form of drawing out the actual triangle. That was a nice touch to really explain things visually. I just remember punching it into my ti89 and getting (123
Thanks, glad it helped clarify things a bit. 👍
Thank you Joe! I’ve been prepping for a test and your channel has been immensely helpful!
Again clear explanation. Thanks and look forward to more from you Joe
There's more on the way!
Thank you too very much, I only wish you were making videos years ago when I struggled with all of this. Excellent stuff. I'll be using your videos to re-educate myself.
Yourself and Jason Simpson from math and science are the best teachers I've come across.
Ah, thakks so much that's really kind of you to say. I love that the videos help people who qualified previously but want to understand more. 😊
Excellent Video. Put in away that is easy to understand.
Thanks Steve, that's always the goal.
crystal clear explanation. Thanks for this. It helps me a lot on my review.
Thanks for this Joe, studying for my radio am exam, very useful
You are very welcome Bob. 😊
@JoeRobinson - You are a God send my friend. Thank you cannot express my appreciation. I'm going to pass this AC class because of you. I love you man!
Thank you so much for this information joe it’s really appreciated & knowledgeable
My pleasure, glad it helps. 😊
I absolutely loved this! Thank you for the great Video!!!!
Glad it helped. 😊
You will help me pass my second year electrical… I can’t thank you enough…. Do you do Canadian code videos? 😊
My pleasure, I'm afraid as a UK electrician I don't know a lot about Canadian electrical code. 😕
This was so great & useful. Thank you for sharing.🙏
My pleasure, glad it helped. 👍
Excellent, as always.
Thanks Mark, more to come!
THANK YOU OMG I REAALLY GOT SAVED LAST MINUTE!!
So so so so so so helpful!! Thank you so much sir
24 minutes time for tea and JR 👍
Ah, enjoy! And stay tuned for more!
Really great content thank you!
Thanks a lot, greatly appreciated.
my lecturer just sent us a link to the youtube searh for "joe robinson inductance" and told us to watch all your videos on it to learn it, we're level 3 btw, college was a bit naff last year so didn't really cover the science part.
If you check out my playlists there's two devoted to the City and Guilds science syllabus, might be worth catching up on anything you're not confident on from last year. Hope it helps. 😕
Dude helped me alot
Good job, nice video :) any videos about RLC series circuit coming?
Sure is, stay tuned for more on a range of subjects including RLC circuits.
It’s Great video MR joe and l want from you continuous in your perfect videos 😂♥️♥️
Thanks, I'll keep trying. 👍
thank you for this!
👏🤩👍
Also helping me study for my Radio licence. Thank you.
Great to know.
excellent man excellent 👍
But could you explain the power factor is lag or lead?
Brilliant 👏
so clear
Thank you!
Thank you very much sir
Joe thanks so much
Very good.
great job
Thanks, stay tuned for more!
Good teaching
Question about true watts, why don't we consider the XL of the inductor when calculating the watts? I understand it's because it's utilizing inductance and the magnetic field provides a certain amount of impedance, but doesn't the inductor also get hot as a result of power? If it gets hot the doesn't it have a watts component?
So nice
Great video, how do you calculate the inductance for a coil on a rectangular core?
Thanks for the videos Joe. Do you have anymore worksheets like the one in the description or is it just for your learners only?
Worksheets are available on individual videos, there'll be more on the way.
Very nicely presented. Apart from the register, the reactance has its own resistance part, which is not considered. Can you please comment. Thank you.
Great …….very great
Thanks
I hope, you have used the pythagorean theorem for that triangle.
c^2=a^2+b^2.
Thanks for your training.
What if the prequency is missing?
You can not calculate anything! No XL and of course of that also no Z.
great video, can you show impedance for a parallel?
It's on my to do list! Thanks for commenting. 😊
How do you find the suitable scale for the triangle
All is cool. But. Why did not we true power multiply cos φ ?
Multiplying by cos theta would give us a smaller number than the true power giving us a circuit that was more than 100% efficient and thus break physics.
@@JoeRobinsonTraining which cases we need multuplying by cos theta?
Eugene P Real power=Apparent power X cos pi
I'm doing everything backwards to find R with only values Xl and Z using Pyth/Recip method
Power factor lead or lag
It's inductive so a lagging circuit in this case. 😊
