Impedance is the complex quantity. XL & Xc are real. Z = jXL for inductor Z = -jXc capacitor You have to study in detail about phasors to understand this. A sinusoidally varying quantity can be represented by a complex number which is the phasor. This representation makes the computation easy. This is the most important topic in AC steady state analysis.
The entire equation has been divided by LC and then the two roots of the quadratic equation can be found using the -b +- sqrt (b^2 - 4ac) / 2a. Where a, b, and c are co-efficient of the quadratic equation.
at 3.33 - Can i power the circuit using a 12v DC power supply ? What should the corresonding Capacitor, inductor and the resistance be get a highest current ?
At resonant condition, the current will be maximum, and it can be given as Imax= V/R (As, wL= 1/Wc).So, Imax^2= V^2/R^2. And Imax^2/2 will be equal to V^2/(2R^2). I hope it will clear your dobut.
errr... at 15:20, the final equation for w1, when you look at the quadratic equation the 1/LC part should end up 2/LC but everywhere says it is 1/LC, so is there a conspiracy involved or am I making a mistake ??? it's 4ac/2a => 2/LC
For the quadratic equation a x ^2 + bx + c = 0 ; roots are -b/2a +- sqrt (b^2 - 4ac)/2a. In this case, a = 1, b = R/L and c = - 1/LC So, fro mthis you will get w1 = -R/2L + sqrt ( (b^2 - 4ac ) / 4a^2) which is equal to w1 = -R/2L + sqrt ( (R/2L)^2 + 1/LC) I hope it will clear your doubt. And you will be able to figure out where you made a mistake. If you still have any question, do let me know here.
The formula that you wrote is for the magnitude of the impedance. With that formula, you are getting the length of the Z side of the impedance triangle. So you are getting a number value with that Pythagorean theorem formula. The formula Z = R + XL + XC = R + j(XL - XC) is the formula for the vector form of the impedance. The impedance is basically divided into two components in that formula, resistance R in the Real or horizontal axis of the imaginary plane (you can visualize it as the horizontal leg of the impedance triangle), and the reactance component which is along the imaginary or vertical axis of the imaginary plane (this is the vertical leg of the impedance triangle).
The quality factor shows how well the circuit is able to select the particular frequency. As I have shown in the video, as the Q factor reduces, the frequency band gets wider. And offers less selectivity. I hope it will clear your doubt.
Resonance is the condition where the RLC circuit is purely resistive in nature and the frequency at which this phenomenon happens is known as the resonance frequency. I hope it will clear your doubt.
Sorry to all who say it's is a good explanation - I can only assume you already understand the topic. There's no explanation at all, only a description of outcomes. If the purpose was to show a student knows how to recount the headlines, well done. It's OK as a revision video, no use as a teaching/learning video.

Sir one doubt, If we want to listen to all the other frequencies as in listening to songs, why can't we use rejector circuit or band stop filter instead of band pass filter?
@@umasrivastava4142 if we use band stop filter, it block the wt frequency we tuned, so all other frequencies are mixed up and we get noise not a song bcz of that we use band pass filter, it only passes the particular tuned frequency
@@ALLABOUTELECTRONICS But when we use the bandwidth formula to calculate cutoff frequencies when resonant frequency is given.... That formula suggests that resonant frequency is the arithmetic mean of the cutoff frequencies
@@ALLABOUTELECTRONICS And one more thing..... So you mean that the graph is assymetric ..... Or the graph shapes on left and right side of the resonant frequency are not the same. So why is it assymetric?
Resonant frequency wr= sqrt (w1x w2). So, it is geomatric mean of w1 and w2. While bandwidth is difference between w1 and w2. And the graph is symmetric.
@@ALLABOUTELECTRONICSOkay I agree with the first part.... It is geometric mean. But if we assume the graph is symmetric on both sides of resonant frequency. Then at a particular value of current we will get two frequencies say w1 and w2, then graphically the resonant frequency will be exactly in the middle of w1 and w2, which means it is the arithmetic mean and not the geometric mean. I'm sorry I'm not able to express my doubt clearly as I can't send a picture or anything here...but pls try to help if you understand my doubt.😄
You can see it in the oscilloscope or you can also simulate the circuit and check the transient results. Every simulation software have the option to see the transient results.
I will update the link for the problems in the description very soon. Try to solve it and if you find any difficulty in solving then I will provide the solution or maybe I will make a separate video on it. I will update it in couple of days.
what a good explanation i just got my complete high school knowledge on this topic refreshed in some minutes .thanks for taking time to make it and post it .
There is a separate channel for that. You can check the second channel ALL ABOUT ELECTRONICS- QUIZ for more examples. Just go through the network analysis playlist on that channel. You will find many examples there.
Because I1 represents the lower cut-off frequency, where the current will be equal to 0.707 or 1/sqrt(2) times the maximum value. I hope it will clear your doubt.
Below resonant frequency, the capacitive reactance will be more than the inductive reactance and hence the circuit will be capacitive. After resonant frequency, the circuit will be inductive in nature.

At last i've found the best video tutorial for resonance in series rlc circuit
This is one of the best tutorials I have watched so far on UA-cam
Omgosh this is the best explanation on series resonance ive ever seen.

Nice explanation sir, tq u so much... But small mistake is their at 12:46 is 2R^2...not 2R..... Tq u for provide to us
Honestly ..d best xplntn i hv ever watched...tq so much sir
This guy right here is the best bro taught me alot in just 19 min ❤️
Today I missed online class about resonance and now i am not worrying about it
Thank you sir. It was just awesome. All doubts cleared.
Thanks a lot sir,u r the best among all videos

In Q equation
For maximum energy stored, why are you considering only L or C at a time
I think we should consider both L and C together.
Because when the capacitor is charging then the inductor lost its energy. they both can't store energy together so, the maximum will be given by one.
@@Vinodkumar-is9sy it is discharging but has some enengy stored at that time
Thank you so much! This topic has been grinding me down for a week but i understand it now.
THIS Tis the best explanation .mind blowing
Sorry if it's a silly doubt but why are Xl and Xc complex?
Impedance is the complex quantity.
XL & Xc are real.
Z = jXL for inductor
Z = -jXc capacitor
You have to study in detail about phasors to understand this.
A sinusoidally varying quantity can be represented by a complex number which is the phasor. This representation makes the computation easy.
This is the most important topic in AC steady state analysis.
Is it the same if i put voltage on the graph?
Would it be Vmax/sqrt(2) for the cut off frequency?
How we got this equation (14:53)?
And thank you
🙏🏻👍🏻
The entire equation has been divided by LC and then the two roots of the quadratic equation can be found using the -b +- sqrt (b^2 - 4ac) / 2a.
Where a, b, and c are co-efficient of the quadratic equation.
Have any lecture about parallel resonance circuit?
Here is link : ua-cam.com/video/mt3WwcQuJSE/v-deo.html
at 3.33 - Can i power the circuit using a 12v DC power supply ?
What should the corresonding Capacitor, inductor and the resistance be get a highest current ?
What a good things to watch during lockdown
Imagine watching this so you can learn about stuff on a test that they never taught you about
Hi
why did you compare the two terms at 12:48??
Because i1 = i(max) / √2 .
You're more helpful than you realize.Thanks A Lot... :D
Can you make video of advantages and disadvantages between series and parallel resonance circuit.
Show that in a series R-L-C circuit f1 f2 = fr² ???
How did you derive Q = (1/R) (sqrt(L/C)) ?

Very nice explaination sir 🙏😊👍👌
And thank you sir for giving the timings of the particular topic in the description box.
where the minus come from in the equation z=r+wL-1/wc?
How do i measure the frequency generated ? What's the name of the device ?
I am greatly aided visualizing this video.
Mind blowing... I can’t thank you enough for this lucid explanation.
Sir , w(omega) is the frequency of source , so how it changed when capacitor is changed . While changing the frequency of the radio.
The source is replaced by The recieved radio signal . And the output is taken across the resister.
Best explanation cleared all my doubts thanks
Sir how come that on 12:57 the 2R^2 that came from imax^2/2 became R^2 only?
At resonant condition, the current will be maximum, and it can be given as Imax= V/R (As, wL= 1/Wc).So, Imax^2= V^2/R^2. And Imax^2/2 will be equal to V^2/(2R^2).
I hope it will clear your dobut.
ALL ABOUT ELECTRONICS thank you very much sir!
15:21 can anyone tell me how did that w1 equation solved

which is equal to w1 = -R/2L + sqrt ( (R/2L)^2 + 1/LC)
I hope it will clear your doubt.
And you will be able to figure out where you made a mistake.

Why current is maximum at resonant ??
Because at resonance, the impedance of the circuit used to be minimum. And from I= V/Z (Ohm's Law), current is maximum at resonance.
Thank you...
Dear sir resonance at
Xl+ Xc=0 or Xl = Xc
Nice explanation
What is the purpose of the quality factor? What is the application?
The quality factor shows how well the circuit is able to select the particular frequency. As I have shown in the video, as the Q factor reduces, the frequency band gets wider. And offers less selectivity.
I hope it will clear your doubt.
How one can say that it is selective in nature while parallel resonance is not selective??
What is j sir?
