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
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 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).
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.
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 .
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.
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.
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 ?
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.
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.
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.
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.
@@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.😄
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.

Imagine watching this so you can learn about stuff on a test that they never taught you about
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

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).

Hi
why did you compare the two terms at 12:48??
Because i1 = i(max) / √2 .
Is it the same if i put voltage on the graph?
Would it be Vmax/sqrt(2) for the cut off frequency?

Can someone explain to me, why we change the capacitor value instead of inductor when we want to change the resonance frequency?
Because sometimes it is difficult to find or design the inductor of the specific value. (Because of the number of turns and diameter)
