Lesson 10 - Practice With Phasors (AC Circuit Analysis)

[@greatestever3037]

Honestly I am not gonna pass

[@OfficialAmmorton]

Did u pass?😂

[@Shaikhaav]

Did u pass?

[@aman_zaidee]

Us bhai us

[@wakeupthisisntreal8168]

Not with that attitude

[@PrincessPresident]

This is me rn 😢😂😂

[@alialrubaey5565]

wow THANKS FOR LEAVING ME WITH BLUE BALLS

[@ichigokurosaki1119]

BEST EXPLANATION FOR A REFRESHER!

[@UnfilteredStar]

I was very confused and frustrated with that representation now you made it clear .Thank you very much sir !!

[@ProGamer-fx2gn]

Great explaination by sir , thanks from Bangladesh 🇧🇩

[@javerialatif5280]

Hopefully found this,Watching this on my final paper day (electrical network analysis subject) this is so easily explained thank you sir, really appreciated

[@sethwilliams3683]

Thank you sir! I was having trouble with the sin portion of it, but I got it now!

[@honestman276]

Thanks. From Bangladesh.

[@fitnessbeasts_]

the recommended vid pop ups at the end of the video block out like half the screen, but thank you for the explanation

[@aduseiyeboah7577]

Man , you do all❤️❤️❤️

[@tomas_soeterik]

So if its sin, i just subtract 90 degrees and thats it? And my phasor is also the amplitude like cos?

[@kokomelon3807]

When do I use Vm/√2

[@kokomelon3807]

I had saw one use it to convert it to its phasor form.

[@nihadhossain8404]

Thank you sir

[@IgnatiusDinlamo]

Good one

[@thabisombingo9649]

i think your graph is out of phase by 90 degrees sine should be 0 degrees and cosine be 90 because as it is you are saying at t=0 cosine is 0 and sine is 1

[@jimhenderson2308]

I think the sinusoid has to be expressed as cosine soas to be consistent with Euler formula as it relates to complex plane. This practical application of phasors was popularized by Karl Steinmetz This duality of nature is present in physics as electricity and magnetism and applied in electric circuits for sure. The capacitor stores energy in the form of an electric field (involves static electric charge) and inductor stores energy in the form of a magnetic field (involves moving electric charge as current). Resistor just dissipates electrical power to thermal power as heat.

[@aaron5305]

Would the phaser voltage be 120.2? Vrms = Vm/sqrt(2) = 170/sqrt(2) = 120.2

[@alhasansony6771]

same question from mine also

[@mvc2020]

Phasor is complex representation of a function. Thus, one uses Amplitude and Angle. While RMS values are used for computing steady state values.

[@mvv.3431]

@@mvc2020 Thank you so much for that comment glad i read it now i understand....

[@WestVision]

thank you.

[@rameesmonk8986]

Can we have two phaser representation for same voltage

[@brenomacedo4774]

Consider the phasor 120V with 90º, its the same as 120V with - 270º You can also represent it as e^( j * pi/2) just remember that pi/2 = 90º U can also represent it as : 120V * (cos(90º) + J sin(90º) )

[@sezarosum3715]

HELLO ANTON!!! ALAM KO NA PANO YUNG SA 2. HAHAHAHHAHAH

[@jc8153]

So... you noticed that a lot of students experienced... inadequate... electromagnetism professors?

[@nishugurung2339]

Try inadequate professors, period. :')

[@robotslug]

Whoever edited this video was a sadist.

[@niteshkumaryadav8022]

Which country sir

[@bommbomer]

ads block your board !!!!

[@osmankaratay5722]

shoudnt it be 90-20 on the last question

[@ajbrewer1777]

Reasonable logic but nope. You subtract 90 from whatever your phase angle is. The reason being cosine is lagging sine by pi/2 (90*). If you subtracted from 90*, you would not be making that full pi/2 phase shift into the cosine domain. You also subtracted a phase angle from 90* for no reason. I hope that helps. Im a student, not a professor, so make sure that the random guy on the internet (me) isnt full of shit.

[@freedomsebastian2546]

😂😂😂😂😂😂 to any question from my circuit theorem lecturer

[@noizebuoy7784]

On a.), Is it possible to find 377 with just the given of 170cos(t-40°)? How?

[@dimitris31]

No it’s not

[@benkasper4035]

quiet vid?

[@adveshdarvekar7733]

+1

[@zoeycruz226]

can you do a video just using sin instead of cos? this vid not really helping much

[@tempestandacomputer6951]

To convert a sine function to cosine just subtract 90 degrees.

[@andramelisa7615]

wtf is that
