On behalf of all EE's worldwide, I thank you for clearly explaining these concepts which teachers go on forever without ever explaining the subject in a precise manner
One clarification: when the pulse is in ON state the voltage dropped across the LED is same irrespective of the duty cycle. How is the brightness of LED or the speed of the motor dependent on the average voltage rather than the input voltage at that instance?
I want to know this too. I dont understand how LED or motor can act different when voltage is still 5V or 0V. Only what change is time in which these two values are in
Very nice explanation and graphics. I assume, to achieve an average current, normally we need some form of capacitive or inductive effect with a time constant, otherwise the current would completely vanish when the pulse is in the “off” phase. In the special case of a LED that probably does not matter, because if it is off for a very short time, our eyes would not notice.
sorry to be so offtopic but does any of you know of a tool to log back into an Instagram account?? I somehow forgot the account password. I appreciate any help you can give me!
@Avery Raymond thanks so much for your reply. I found the site on google and Im in the hacking process now. Looks like it's gonna take a while so I will get back to you later when my account password hopefully is recovered.
To control the speed of induction motor can we use a speed controller scr and pmw module to enhance the impact of given voltage on induction motor ! Great explanation for the above tutorial 👍🔝🔝🔝
Jazakallah ( may ALLAH reward u fr this ), ur effort is impressive Can u pls upload vedios on induction heating and dielectric heating And also can u upload vedios on solar & wind genaration Specially on angles like azimuth angle etc. Plssssssss if it z possible
i need to buy PWM for hydrogen production. Hydrogen unit need 220volt 2500watt. I have 220volt inverter. Which bridge rectifier and capacitor should I use to convert ac to dc how to connect capacitor. Which PWM should I selected
@@ALLABOUTELECTRONICS thnku sir , can u tell me y MOSFET or other semiconductor devices r used with pwm pulses ? Before sending it to the induction motor
In PWM, the width of the pulse is varied right! Now, if you take the average of that pulse train ( let's say through RC filter), then it gives average value. If the pulse width is more, the average value will be more and vice a versa if it is less than average value will be less. So, using PWM it's possible to change the average value of the voltage, which can be given to some other circuit. I hope it will clear your doubt.

Really,you proved that electronic subject is not a boring and tough subject. Only need the teacher who explain it clearly,and no doubt it is you.
Fall in love with your teaching style Guruji....plzz help me in my Gate exam by providing all these crystal clear concepts..
u r an Indian Teacher , namathe guruji
A Beautiful and a concise explanation.
Teaching method very simple and excellent thank you
You provide with the best explanation , worth appreciation!

@Avery Raymond it did the trick and I now got access to my account again. I am so happy:D
Thanks so much, you saved my ass!
@Peyton Emmitt no problem =)
really appriciative video
Very helpful, thank you so much , so helpful, u r so great
Very explanatory.I love it .Thanks
Beautiful explanation sir. Thankyou so much
Very clear explanation.,great
Fantastic video ! Very clear and easy to follow.
Thank you so much sir. This was so helpful.
Thank you for the wonderfull lecture.
I liked the way u taught the stuff! Thx-

Plssssssss if it z possible
Thank you ... Now it's cleared
Very nice explanation. Please make videos on Arduino basics and simple Arduino projects.
Excellent. I want to see you sir.
At. last. l. clear. Think. Sir
Best explanation.👍🏻 Thanks a lot sir
Great video! Thank you. And thank you for the captions.
Super sir
Thank you sir
Nice 3xplanation thankyou
Great video!
Excellent ❤️
Thanks! Nice and clear!
Very good thank you.
Wow 😳
Very useful
Good
Thank you very much !
Understood !
thanks you sir ji.
i need to buy PWM for hydrogen production. Hydrogen unit need 220volt
2500watt. I have 220volt inverter. Which bridge rectifier and capacitor should I use
to convert ac to dc how to connect capacitor. Which PWM should I selected
Sir, please put the video for Transducers and it's types
nice explaination
Clear explanation. (
Thnk u sir
Perfect presentation, but while switching the mosfet that are in parallel to each other what will happen, I think the current would not be sufficient.
Sir can u upload a video on project called temperature controlled fan speed
And how pwm pins of Arduino are operate the speed of motor fan
Very good
Thanx a lot.
Can you describe the microwave system in your next lecture?
Please describe how to get average voltage of three phase inverter.formula explain
great thanks
nice
Is it true that if I want to use a pwm to control a 24 volt DC motor I have to have a 36 volt DC power supply
Different about using arduino and IC555
are you from IIT?
Yes.
Wow
Transistor and amplifier plz
Anyone else have to play this in slow motion to understand this dude ? why is this video 9:11 long ? Illuminati confirmed ???
2:20 sir can't we use a capacitor at the end of the switch to make the voltage output stable ?
If we need the stable average output, then yes we can use the RC averaging circuit.
Thanks sir your explanation is awesome
👍👍👍
Sir can I use pulse width modulation to control speed of induction motor ?
If u read this comment pls reply fast 🙏
Yes, the PWM can be used for speed control of induction motors.
@@ALLABOUTELECTRONICS thnku sir , can u tell me y MOSFET or other semiconductor devices r used with pwm pulses ? Before sending it to the induction motor
I m using 555 ic astable mode
How voltage is varied using PWM
