Thank you so much bro... Tommorow I have seminar...And she didn't explained that....We have to search the topic in net and tell the seminar.... Thank you so much
sir you are not explaining clearly . at every new step you should tell the reason / definition/ and many more . some students are not much talented . so plz this is my humble request to work on these problems as soon as possible . thank you' ,
Many many thanks brother. U made me understand the whole semiconductor chapter in just 2 hours. Tommorow is my exam and it was very helpful. Nice explanation. 👏🏻👏🏻👏🏻♥️♥️♥️
Sir in my notes capacitor is before load resistance.....bcoz we hve to filter it before drawing But still anybody can understand at once by ur teaching sir
hi..thanks for the lession....when you say the half wave rectifier is 47 % eficient...i understand that we only get 47% of the power through...but would it be true to also say 53% of the power is not actualy used or wasted or lost?...im thinking the word eficiency is the wrong word...becaus what we dont use is not lost its just not being used when it is in the turned off situation. for example if i turn a tap on above my glass on for 1 second then i turn the tap off for 1 second we can see the tap is 100% eficient for 1 second and 100% eficient for the next 1 second becaus no water is wasted or lost.
Hello! You are the best ❤ but please I need you to solve series exercise on both half wave and full wave rectifier. Please I should have exams next week. @innovator from Sierra Leone
Dear sir, If i will lighting a string of leds, each led has drop voltage 2V. I use half rectifier with Vac(rms) 220V, how many led can i use in series for 1 string ? and then what is the value of resistor to limit the current to be 15mA ? Please explain step by step include the formulas ? Thanks
3:44, can you explain why the output wave [right] is not covering the entire space from t=0 to t=T/2 ? And numerically small the the time-gaps between t=0 and start of DC pulse and between end of DC pulse and t=T/2 ?
Because during that small initial period, the input voltage is less than 0.7V. And because of that, the diode is not conducting. Since, it is not conducting, it will act as an open circuit. And hence, the output voltage will be zero for that duration. I hope, it will clear your doubt.
The RMS value depends on the waveform. For the half wave rectifier, it is Vm/2. For the full wave rectifier, it is Vm/√2. I hope it will clear your doubt.
sir whenever anode and cathod have same voltegae then diode should be switched on ..but in case of rectifiers u were saying diode would be open swotch,how it would be sir?
To turn on the diode, the voltage at the anode should be more than a cathode terminal. (to be precise, it should be more than the forward voltage drop or the threshold voltage of the diode)
i have a question 11:55 how does the capacitor charged upto Vm in just half circle of time period and in the other side it is not discharging in the same time. and in the second yime why the charging graph following the sin graph? why it is discharging as a linear function( because of RC>>T?)
Yes, it will depend on the RC time constant. If RC time constant is much larger than the time period then capacitor will discharge less and it looks as if it is discharging linearly.
For a sinewave, the RMS value is Vm / √2. For the half-wave rectifier, it is Vm /2. For derivation, you can check this video: ruclips.net/video/A2SMI31EgMA/видео.html
I have made a separate video for the proof of the formula. Please go through the playlist diode and diode application on the playlist page of the channel.
The output would be pulsating DC. It won't be exact DC signal. After one diode, ( depending on how the diode is arranged) you will get either positive or negative half cycle of the sine wave. After passing that signal through the filter circuit, we can get the DC voltage. ( Still It will have ripples)
As I mentioned in the video, if the sine wave is applied as an input, it only allows only one half cycle to pass through it. (depending on how the diode is connected). So at the output, there will be only either positive or the negative half of the sinewave.
You can turn of the subtitles manually. In the video setting, you can turn it off. On the desktop, you can also drag the subtitles anywhere on the screen. I hope it will help.

Sir please attach PDFs of topics explained in the video. It will be very very useful for us. Please sir.
Dear sir,
If i will lighting a string of leds, each led has drop voltage 2V. I use half rectifier with Vac(rms) 220V, how many led can i use in series for 1 string ?
and then what is the value of resistor to limit the current to be 15mA ?
Please explain step by step include the formulas ?
Thanks
Thank you sir .It's well defined and please upload physics videos frequently..
Sir @8:51 ripple factor r is *Vrrms/Vdc* not *Irrms/Idc* small mistake but a significant one. Thank you for this course you saved my life.
Your explanation is nice, thanks.
May you explain transformer utilization factor in HWR?
The formula for ripple in half wave rectifier is wrong, it should be Iac in the numerator instead of Irms.
It's the RMS value of ac component of output current
Your videos are very helpful...thanks for sharing these!
Thank you very much. It's really very helpful.
Hi Dude, your videos are very good. Do you have the related pdf notes too?
will provide it soon.
Well explained mahn
Thank you 🙏 so much
Great work

can you please tell me how to apply the filter
At 6:26 should it not be V/root 2 ? Erms is E•/root 2
good 👍 explanation
wah
tacod betul
Thank you very much sir!!
Please upload the video in 240p and 360p also.
Is there any problem if phase and neutral lines the input of the rectifier get swapped
Nice video really .. we wait more from you
It was helpful
And I have subscribed ur channel
Well explaind
Careful he's our hero
it really helped , bless u
Thank you! ☺
What's the exact value of RMS voltage? V/√2 or V/2. In other video it's shown asV/√2 and in this video it's V/2.
The RMS value depends on the waveform. For the half wave rectifier, it is Vm/2. For the full wave rectifier, it is Vm/√2.
I hope it will clear your doubt.
@@ALLABOUTELECTRONICS Thanks
Before I haven't seen the derivation.
Very very nice sir ji
Just Excellent ❤️💜💙
Thanxx sir u are best
sir whenever anode and cathod have same voltegae then diode should be switched on ..but in case of rectifiers u were saying diode would be open swotch,how it would be sir?
To turn on the diode, the voltage at the anode should be more than a cathode terminal. (to be precise, it should be more than the forward voltage drop or the threshold voltage of the diode)
good tutorial
Superb sir
i have a question 11:55
how does the capacitor charged upto Vm in just half circle of time period and in the other side it is not discharging in the same time. and in the second yime why the charging graph following the sin graph?
why it is discharging as a linear function( because of RC>>T?)
Yes, it will depend on the RC time constant. If RC time constant is much larger than the time period then capacitor will discharge less and it looks as if it is discharging linearly.
2:40 there really needs to be an explicit ground connection for that to make sense.
Good explain sir thanks
Sir at 6:35 Vrms should be Vm/square root(2)
For a sinewave, the RMS value is Vm / √2. For the half-wave rectifier, it is Vm /2.
For derivation, you can check this video: ruclips.net/video/A2SMI31EgMA/видео.html
Thank you 😊❤️
Thanks 🙏❤
Great👍
I wonder why RMS Value is Vm X 0.5 and not Vm X 0.707.
Frank
Thank you sir
how do u proof the formula?and wat is the period of the havf wave rectification graft?
I have made a separate video for the proof of the formula. Please go through the playlist diode and diode application on the playlist page of the channel.
Diode will remain forward biased even when capacitor discharge at positive half cycle- Rectifier circuit
But, why load resistor is used in circuit ???
Nice explanation.....
Awesome
Man after one diod, Current will be AC or DC ?
The output would be pulsating DC. It won't be exact DC signal. After one diode, ( depending on how the diode is arranged) you will get either positive or negative half cycle of the sine wave. After passing that signal through the filter circuit, we can get the DC voltage. ( Still It will have ripples)
Does Vm mean max voltage?
Yes, its the maximum voltage of the sine wave.
Why input frequency equals to output frequency in half wave rectification?
Because the output waveform repeats itself at the same time as a sine wave repeats itself. Plot one on top of the other and you will see.
Why the output of half wave rectification fall in pulses?
Why should we use only silicon voltage
Because most of the diodes which are being used are silicon diodes.
Sir ripple and PIV samajh nahi aa raha😭
good boy
excellency your honour
Hi Sir! How can we get a negative wave only?
Just reverse the direction of the diode.
@@ALLABOUTELECTRONICS OK THANK YOU !!!!
What will a half wave rectifier produce
As I mentioned in the video, if the sine wave is applied as an input, it only allows only one half cycle to pass through it. (depending on how the diode is connected).
So at the output, there will be only either positive or the negative half of the sinewave.
nice video
can we have pdf notes dude
Superb!!¡
There is some mistake in summary. Efficiency of half wave rectifier is 40.6% but in the summary there is 46% 😅
Yes, that's true. By mistake, it was written as 46 % instead of 40.6%.
Tq
Can you provide notes
Yep
best ever
RMS voltage is not Vm/2, it's Vm/root2
For half- wave rectifier, it is Vm /2.
For more information, please go through this video:
ruclips.net/video/A2SMI31EgMA/видео.html
You forgot to multiply the efficiency by 100
very halpful
we want half wave rectifier numerical problems
It has been covered on the second channel. Please check diode and diode application playlist.
Jumps to much doesn't proceed systematicly zzz...
Plz put subtitile
I am in class 1 still i understand rectifiers
I'm in kg and I do too
In summary table efficiency listed is wrong
Sir Whatever ur writing is not visible because of those subtitles can u please see to it
You can turn of the subtitles manually. In the video setting, you can turn it off. On the desktop, you can also drag the subtitles anywhere on the screen. I hope it will help.
