Real, Reactive, and Apparent Power Analogy

In power transfer, there are three types of power: real, reactive, and apparent power. Here is a "sending a package" analogy for understanding these types of power. The power triangle is also introduced, with real power on the real axis, reactive power on the imaginary axis, and apparent power as the hypotenuse.

Whys everyone in love with the analogy ! I see it doesn't answer the main question [WHAT IS REACTIVE POWER ] !

[@scr_scr]

No one can answer bcz it's not really existed ..it's imaginary

[@francismannion7075]

Wow! That was a very creative presentation, thank you Dr. Kim.

[@blueberet7272]

Thank you for such an intuitive and logical explanation for clearing my doubts.

[@user-cy2yu6rf6p]

This is a awesome analogy! Thanks

[@kcmichaelm]

Very straightforward explanation. Thank you!!

[@BatmanDream]

Thank you for this, its cleared up a couple things i was unsure of, also I love the analogy, as I've not heard one outside the beer analogy, yours makes more sense.

[@sandhoshkumargs7967]

your explanation makes me happy.. bcz your concept are very simple to understanding

[@mnada72]

I love this analogy.

[@NiHaoMike64]

I heard a variant of the packing analogy in networking class, with respect to protocols and overhead.

[@debasishmajhi687]

That's a great explanation indeed

[@dannyjix5122]

It's great to see your video.but ma'am I am having some issues regarding my final year b tech project.I wanna know how can we synchronize the solar palnt power to the grid supply (after converting it to the AC)??

[@zakariachahboun]

Thank You and Keep Going!

[@tedlahm5740]

Question please. We are calling it (P) real power, when others call it Active power. Which is a RESISTIVE LOAD. Thank you.

[@abusayeed6318]

Absolutely amazing

[@squishypandaelephant]

Very helpful, thank you.

[@enriquegonzalez2802]

Thank you, madame :)

[@hetanhawke1695]

you are the best Ms

[@s.m.talhawadood5852]

Thanks a bunch Mam

[@Vyktor992]

thank you for this analogy!

[@sihemprincess1955]

Welcome back

[@juanalonsopajuelochipana1922]

where i can get one Valerie??

[@honestman276]

Thanks. From Bangladesh.

[@RaviShankar-ct7gi]

waiting for further lectures

[@laurent9255]

So it is just a complex value .

[@hammad3548]

why is it necessary to have reactive power?

[@struanmurray2625]

Voltage and current don't always line up perfectly as a result of capacitive and inductive components in a circuit. This means that despite having a 10 V, 10 A AC supply (100 VA), some of the power may be unusable because the instantaneous power is the multiple of two sinusoidal waves (P = IV) which are out of synch. Note this is only the case with AC currents, DC currents are unaffected because there is nothing to align.
