- In this video, Resonance in the Series RLC circuit has been explained.
So, in this video, what is resonance in series RLC circuit, and what are the different parameters (Q factor, Bandwidth) related to Series RLC circuit has been discussed and in the later part of the video, expression for the resonant frequency, Q factor and Bandwidth of the Series RLC circuit have been derived.
What is Resonance in RLC circuit?
Resonance is the phenomenon in the electrical circuit, where the output of the circuit is maximum at one particular frequency.
And that frequency is known as the resonant frequency.
At the resonant frequency, The capacitive reactance and inductive reactance are equal. ( XL = XC), and the impedance of the circuit will be purely resistive. Not only that, but the value of impedance will be minimum at the resonant frequency. And hence the value of current will be maximum.
So, this series RLC circuit provides the tunability at one particular frequency and this principle is used in radio communication for channel selection.
Now, to define the selectivity of the resonant circuit, two parameters are widely used.
1) Q factor
2) Bandwidth
Q-factor:
Q-factor defines the sharpness of this resonant curve, or it defines the selectivity of the circuit.
It is the ratio of energy stored in the reactive element in the circuit to the energy dissipated across the resistor in the circuit.
So, larger the value of this Q in the circuit, the better the selectivity provided by the circuit.
Q= 1/R √(L/C) = wL/R= 1/(wCR)
Bandwidth:
The bandwidth of the circuit is defined as the difference between the -3dB frequencies or half power frequency.
The smaller, the bandwidth of the circuit, the better will be the selectivity provided by the circuit.
B.W= R/L = w/Q
The timestamps for the different topics which are discussed in the video is given below:
0:45 What is Resonance in the RLC circuit?
7:15 Quality factor
7: 57 Bandwidth of the series resonant circuit
9:19 Derivation for the expression of resonant frequency
11:36 Derivation of bandwidth of the series resonant circuit
16:57 Expression of the Quality factor in terms of the circuit parameter.
This video will be helpful to all students of science and engineering in understanding the concept of resonance in the series RLC circuit.

At last i've found the best video tutorial for resonance in series rlc circuit
Omgosh this is the best explanation on series resonance ive ever seen.
Thank you so much! This topic has been grinding me down for a week but i understand it now.
Thank you sir. It was just awesome. All doubts cleared.
The downloadable link for the problems on the Resonance has been updated.

where is the solution of these numericals
Solution?
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
@@shrinivash1578 thank you sir
This is one of the best tutorials I have watched so far on UA-cam
Its my first time saying 'WOW' after watching an educational video! Seriously, thank you so much.

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 ?
Thanks a lot
Very helpful
It is really helpful for my exams tomorrow, Thanks for such easy explanation..
sir thank u so much for ur videos but o kindly request u to explain with few more examples in each topic
Nailed it bro 🔥
Good explanation sir
All about electronics thank you very much thank you 🙌 and o
Thank you so much
Good work🤗
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.
thanks your explanation is very good but mujhe thora fast laga I hope you will not mind and also thank-you for your suggestion
download video and open video in vlc.. and press "numpad minus -"😂

Sir To creat wireless power transmission circuits how di create resonance frequency 50hz 12 v ac
Excellent
thank you
best💙
👌👌
Thanks you so much broo
omg
wow
no words
u r lit sir
please tell me how to thank you
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.
Sir
very good explanation,fantastic,,,,,,,
sir may I know What software you use to teach (I mean for writing)
pen tablet
Sir,thank you for your kind reply, sir I want know the software you use with your pen tablet,
and also pls tell me the brand of pen tablet
Super bro
How do i measure the frequency generated ? What's the name of the device ?
Show that in a series R-L-C circuit f1 f2 = fr² ???
where the minus come from in the equation z=r+wL-1/wc?
Thank u sir
17:38
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
What is the difference between resonance and resonance frequency. .......plz help me
Hii sir
Plz make video on frequency range of series and parallel rlc circuit..
Thanks for the vid today is me electric exams gir matric finales
Good luck
Thank you so much sir ...can you please upload some problems on series and parallel resonance??
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.
The downloadable link for the problems on the Resonance has been updated.

Tell 2 to 3 examples for every topic which u had told in the past
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.
How one can say that it is selective in nature while parallel resonance is not selective??
May Allah bless you! Thank you so much!
What is the application of series resonance? Please give examples.
Thanks
