Top bloke this guy. His videos are better than my college.

[@PunmasterSTP]

Inductive reactance and impedance? More like "Informative lectures that are simply the best!" 👍

[@thefoodcan]

My professor is awful at teaching and your videos have gotten me through the semester so far, thanks.

[@linandy1]

Isn't it awful how we pay for all these awful professors 😡

[@PunmasterSTP]

Out of curiosity, how'd the rest of the semester turn out?

[@sorrygtfo]

thanks mark wahlberg

[@cloviscareca]

Dude, this video explain everything I've always wondered. Thank you so much

[@irishchocolate3872]

It is interesting. In practically all your videos on circuits, you use no trig or complex number representation in calculating power factor, power factor correction, phase angle etc. I go to Engineering Academy and when he is covering some of the same topics he is using trig and complex numbers to do the calculations.

[@thefoodcan]

I believe you do trig when a capacitor is introduced to a circuit.

[@ltmcmuffinz8561]

I really appreciate your videos, you've been an amazing help in my schooling

[@shreebohara9943]

This is the best video i have ever seen❤️❤️. By spending 2000 dolars for coaching and couldn't understand a thing.

[@offspringfan1288]

In my 3rd semester of Mechatronics. Enjoy your video bro!

[@dhruv28786]

Yeah and im in 12th grade learning this lol

[@DorothyEnomb-zq2ti]

My best teacher ,your even better than my teaher at school💯❤️

[@emmanuellerigorm.rubiano4983]

Sir, Thanks! Means a lot! You deserve it!

[@TheRealRade909]

You could also calculate the power consumed by the circuit with a third solution by squaring the voltage across the resistor then dividing by the resistor! P=[(Vr)^2]/R P=[(9.585V)^2]/50 ohms P=1.837W

[@inambaomartin5782]

This video has helped me a lot

[@chibspro]

Bro is a genius

[@MARK-jo9vw]

Thank you!i have a electrical Principal exam tomorrow 💪

[@RAndrewNeal]

What I want to learn is where these formulas came from, not just how to use them.

[@myintnaing2470]

Sir. Think. for. such. a. good. teaching

[@yanavassilyev9291]

why isn't voltage across the inductor not referred to as the induced emf as it was in DC? and doesn't use -L*dI/dt? would the inductor try to counteract the falling and rising of the current during alternation in the same way?

[@yanavassilyev9291]

I feel like I have it all backwards

[@howcreated_ideas]

Nice tutorial

[@faridjaafar2605]

When should we convert to mili amps?

[@amikhimji]

VERY NICE EXPLANATION THANK YOU

[@niobeeyt4889]

Thank you.

[@angelofranklin1]

Great vid thanks

[@klipk7296]

In the first circuit, do we assume that the 12V source is labelled as Vpeak?

[@neatvfx]

hey...why we need to assume Voltage as rms value...it is not given so..So how u take V as Vrms ?

[@manasijvs5486]

sometimes its like this guy knows everything

[@mahanth2907]

The video examples were great! However, wouldn't the Irms = Vrms/Z, since Vs != Vrms and Vrms is found by taking the average value of the function sin(theta) over the interval from [0, 2pi]. Therefore, Vrms = sqrt(ave(Vm^2cos^2(wt)) = sqrt(Vm/2) = Vm/sqrt(2) = 12/sqrt(2) = 6sqrt(2). Doing the calculations for rms current, Irms = Vrms/Z = 6sqrt(2)/62.2 = 0.136A

[@possibility28able]

Why is 100 raised to the negative 3rd power?

[@qritikk]

because it as m infront of it to represent milli

[@djandcj]

Great explanation wish I had it 10 years ago 😂

[@musicsoul2127]

Thanks..

[@kazitaukirahammed5806]

What abou the pawor factor

[@rakeembluitt2290]

So how about if you have no given frequency in the equation?

[@clozano6799]

You can't calculate XL without frequency, so they at least need to give you enough info to calculate frequency as a first step.

[@sh115067]

There won't be any reactance. It's directly related

[@jackwithrington5988]

A series circuit consists of a capacitor and a coil connected to a 120 Volt, 60 HZ supply with the following values: 1. The coil has a resistance of 30 Ohms 2. The coil has an inductive reactance of 40 Ohms 3. The capacitor is 15 microfarads The circuit current is _______ Amps. A) 4.00 B) 2.40 C) 0.957 D) 0.857 please help

[@jackwithrington5988]

With working pleaseeee

[@santoshkumarsingh5304]

My answer is coming out to be (D)0.857 Is it correct? Plz confirm

[@Egirl_Slayer]

0.857

[@qritikk]

when finding power why didn't you use impedance instead of the regular resistance

[@howcreated_ideas]

Watch also our videos more clearly

[@zaidsalama4804]

Thunk u .

[@mdonoCFC]

Why do you put a line through “Z”?

[@lestahass8849]

So not to confuse it with the number 2

[@habibah9062]

thanks man

[@merrymay681]

What if I had another leg beyond what you have already?

[@poliwog1817]

Wait a sec, are we assuming that it is 12VAC rms?

[@LolIGuess123]

Yeah this was done incorrectly

[@orangaharris640]

This doesn't show you how to punch equations in our calculators .I somehow can't get -3 on my calculator

[@Fufu-x4v]

Have u figured it out yet?

[@MadeAnointed7]

I thought power was current times voltage. Shouldn’t power be 2.3 watts?

[@jasonlee3247]

This only applies for DC circuits. The reason it doesn’t apply to AC is because inductors and capacitors cause the voltage and current to be out of synch. If you look at the voltage and current waveforms on an oscilloscope, you’ll see that when the electricity flows through an inductor the current becomes “delayed” with respect to the voltage.

[@hossamhafez9826]

​@@jasonlee3247 exactly must be observed that Ac squared plan Xc

[@merrymay681]

I'm not trying to find any capacitance whatsoever just an RL Parallel circuit set up just the way you have drawn your circuit.

please turn up your microphoneso so we can hear you without having to turn our amps up full blast.

How does phase shift occur in a single inductor? What happens if a resistor were to be included? Classical analysis does not provide answers to these questions in an intuitive way. To understand the reason for phase shift in inductive circuits Faraday's law should be applied. This can explain the co-occurrence of a non-Coulomb electric field with a changing current in the inductor. Also, a Coulomb electric field appears and this is hard to explain unless one takes a unified approach to electrostatics and circuits. How does phase shift occur in a single capacitor? What happens if a resistor were to be included? Classical analysis does not provide answers to these questions in an intuitive way. To understand the reason for phase shift in capacitive circuits, a unified approach to electrostatics and circuits will be useful. Electrostatics and circuits belong to one science not two. To learn the operation of circuits, Current and the conduction process, resistors, capacitors and inductors and how discussing these topics with a unified approach makes it easier to understand phase-shifting in capacitive and inductive circuits, watch these two videos i. kzbin.info/www/bejne/iHbWiJeabJukrsU and ii. kzbin.info/www/bejne/bnO0fpKurJeFnNE The last frame References in video #1 lists two textbooks 3 and 4 with topics that discuss the operation of capacitors, inductors including phase-shifting with a unified approach to electrostatics and circuits. The results of simulation runs usung TINA software of circuits that superimpose ac signals on dc voltages “Simulation_super_ac_sig_on_dc_volt.pdf” and of CR phase-shifting networks typically used in RC Phase shift oscillators “RC phase shifters.pdf” are included in pdf files in the CD which is included with textbook 4.

Very low audible

[@successthruknowledge]

He doesn't explain the meaning of the power factor in this video or an earlier one. Power factor is an expression of energy efficiency. It is usually expressed as a percentage-and the lower the percentage, the less efficient power usage is. PF expresses the ratio of true power used in a circuit to the apparent power delivered to the circuit. A 96% power factor demonstrates more efficiency than a 75% power factor. PF below 95% is considered inefficient in many regions.

[@Salamanca-joro]

There is a lot of videos about these where he talks about ac circuit and electric current and related topics, you gotta watch them all to understand these question , he explained them before

[@successthruknowledge]

@@Salamanca-joro yes I am further along in his playlist and I see that he does explain power factor in a later video though thanks!
