Why do Purely Inductive and Capacitive Circuits Not Dissipate Any Power?

[@craigemmott4976]

Even though I've passed my L3 science and electrical principles exam, it's still great to watch and learn from your videos Joe.

[@JoeRobinsonTraining]

One of the most rewarding comments I've ever had, passed the exam and still watching! Thanks so much.

As we have come to expect from you. Fantastic GRAPHICS which helps tremendously with your vocal explanation. Thank you.

[@JoeRobinsonTraining]

Thanks for the feedback Ted!

[@no_short_circuit]

Thanks Joe, well explained and I understand it. I've always wondered about this stuff but never really understood it until I retired and started to look at all things electrical as a hobby. Your videos have been a great source of learning. What is the software you use to draw your graphs? Is it freely available?

[@JoeRobinsonTraining]

Glad you've enjoyed them. I use a website called Desmos.com, great software and free to use.

Thanks Joe, great video - literally a light bulb moment - which got me thinking and reading about inrush currents and switch off spikes in inductive and capacitive circuits It would be great if you could look at those some day!

[@JoeRobinsonTraining]

Ah, so cool Adrian glad the videos help. I'll add your suggestion to my to do list!

[@GSHElectrical]

First to like 👍. Great video Joe

[@JoeRobinsonTraining]

Cheers G!

[@diatribeeverything]

This is great stuff. Thank you. Please keep it coming!

This AC Theory series has been extremely resourceful. I found it surprising how incredibly enlightening these lectures have been for me considering my knowledge of electronics for the last 30 years. I'm stoned how I have overlooked the importance of Power Factor and the Average Power Dissipation of Reactive components like the inductors and the capacitors: Even though I knew most of everything in your lectures, after going through all the videos on AC Theory, I feel like I knew nothing. 😆😆😆. Thanks Joe for your amazing eye-opening lectures. You are a true professor.

Great Vid. Thanks Joe. You can achieve superconductivity at room temperature with the right set up. Have an LC circuit that's in resonance and with high frequency, you'll have zero resistance.

[@JoeRobinsonTraining]

Interesting, I didn't know that, I'll look into it thanks.

[@YangobingYana-d6r]

The concept just sank into my brain. Thank you Sir!

[@D0li0]

Great video.

[@JoeRobinsonTraining]

Thanks much!

[@gbelectricks]

I just watched this video again, we need more Joe Robinson content in our lives!! You seem to have slowed down with your own content?? Please sir can we have some more?😁 One question, if I put a clamp meter around a capacitor “leg” I measure an amperage, so what am I measuring? Is it current being drawn into the capacitor, or current being dissipated, or a mixture of the two?🤷‍♂️

[@JoeRobinsonTraining]

More content on the way matey. I'm also producing my own content on eFIXX as you know. 😊 Stay tuned for more. Great question on the capacitor you're measuring the rms of the current flowing in and out of the capacitor. This will vary depending on the capacitance and frequency of the circuit. 👍

[@SchaumaMan]

These are awesome- you are a life saver Joe :)

[@JoeRobinsonTraining]

My pleasure!

[@sadiarehman9175]

Hello ! Can you write the function which you have graphed through this software you are using ? Will be grateful. Thanks.

[@JoeRobinsonTraining]

Send me a DM on social media and I might be able to send you a link.

[@jbhench]

Carnt thank you enough for these videos really helpful 👌🏽👍🏽

[@Studybuddy_100]

That's really helpful to us ,thank you verY much sir.

[@JoeRobinsonTraining]

It's my absolute pleasure.

[@kalumprasannaHW]

Mr Robinson ,as residence power meter s are kWh meters , we are not paying for the apparent power isn't it ? Only in place s where VAr measure ments are carried out have to pay . Am I correct ?

[@max_galingumas9409]

residential homes produce tiny amount of reactive power so power companies do not charge for that

[@SiverKareba]

Please could you tell me what the interval(period) you have chosen in (💚N, power wave) I can only see {0 Great video, thank you.

[@suhailawm]

Wow. Tnx alot

[@JoeRobinsonTraining]

You're welcome!

[@Swaggarization]

Is it possible to make the whole household current, shifted 90 degrees? And if so, how?

[@JoeRobinsonTraining]

You could install a massive beefy array of capacitors, not sure why you'd want to? 🤔

[@Swaggarization]

@@JoeRobinsonTraining Thanks for your swift advice! 1. That should be parallel on the 230 V I guess? 2. I am curieus to find out what my digital KWh meter will register. That’s why I want to do this experiment. If the phase is shifted 90 degrees, there should be a different measurement, isn’t it? 3. Furthermore I wonder how to calculate the exact Farad amount at say 10 Ampere. 4. But I also guess that with a more existing load that is i.e. more inductive, the compensation should be different and effects the amount of Farads needed to do a maximum phase shift of 90 degrees. 5. Why a massive amount of capacitors? And not a single big one? Thanks again for your help, knowledge and instruction efforts!
