Hi, thanks for the video, I have a question, I'm new to electronics: 1- Isn't each single LED current should be ~ 18ma but your whole circuit measured 14ma? this mean you should put x8 more current through the circuit? or you just put a low load here? 2- Which part of this circuit turned the 240v to 24v AC? The capacitor and the 1m ohm resistance attached to it or the capacitor and both resistance, the 1m ohm + 560ohm? 3- wouldn't;'t it be better if you put the bridge early on the circuit instead of the middle? 4- What does that symbol in the capacitor formula mean? the 2x 3.14
I made this circuit after waching this video but circuit giving 50 volt output across the dc terminal..then how can i use this ? And one more thing is diodes getting hot.so please give me ur valuable guidelines. Thanks
Brilliant explanation, sir will it be possible for you to explain the RF module transmitter and receiver circuit step by step every components used with all calculations etc. eg. 433 MHz transmitter and receiver module circuit every components used and working 🙏
Very impressive one. I need same but with 8mm leds lights with 5/6 number of leds light,what are the components need to used? Sir,please give me details,Thanks & Rgds Hari
Sir pls tell the calculations for the second capacitor as well that is why 100uF? which is connected after rectifier. I need 36V output ,so will the values of resistors change for different output?
Welll done though a warning should be given..........this circuit can cause injury or even be fatal....IT IS LIVE MAINS VOLTAGE. Even a 0.2 cap will cause a jolt if touched.
Thank you! You helped me a lot with your explanation about C, Z and R calculations. I am learning electronics and I want to become an electronic engineer. I Suscribed to your channel. I hope to learn a lot of this wonderful world on electronic and electricity. Regards from Venezuela
Конденсатор на 35 Вольт заменить на 400 Вольт или поставить параллельно ему разрядный резистор, чтобы при обрыве цепи светодиодов не пошло через конденсатор 220 вольт и не было взрыва.
Formula for LED resistor is R = (Supply voltage - LED voltage) / LED ampere. So, R = (220-2)/0.02 = 11k but when I connect 11k with glass type transparent LED then it fuses after sometime. Why?
@@ccv3237 that i didn't include but that's not the case here. Even using higher resistor values like 300k won't save the led. The only solutiin is yo use a diode, that's it!

I guess it's kinda randomly asking but does anyone know of a good site to watch new movies online ?
Really helpful explanation!
Now I think I have the knowledge to be able to resurrect a few failed LED lightbulbs.
You are a very nice teacher....everything is clear !!
Thank you
You are always blessed by your parents. Keep it up in teaching others
Thanks
I am amechanical engineer & you taught as my mathematics teacher during my school days. You are very logical & God bless you.
Thanks
Pl make circuit for 12 & 5 volt led circuit.
Excellent teaching god bless you

Wondering if these older videos can be subtitled? I believe it can help more people.
Very nice Video Sir, can you explain for polar capacitor value calculation.
Very good and illustrative! Thanks!
What amazing video and explanation sir, god bless you .
Thanks
Very clear professional explanation.👌
Thanks
you are genius bro....
Good lesson. But very dim. Is it possible to increase z intensity by changing z Components? How.
Bohot acha video hai
Thanks for the explanation, but what circuit we should use for load having higher ampere rating?
will u make another video for that?
For higher amps ( more than 1A) I will suggest to use SMPS or transformer
Thanks for explanation very understand sir
Very helpful bro,carry on.We need more like this🌷🌷🌷🤩🤩🤩
Thanks for the feedback
Very well explanation. Thank you very much. Thousand like.

Very good really like your explanation. Can you share how to build stable circuit to glow 50 led bulbs like you did glow 8 leds. Thank you in advance
Nice
Thanks
what is the role or 560 ohm resistor and how do we calculate ?
thanks
Sir pls tell the calculations for the second capacitor as well that is why 100uF? which is connected after rectifier. I need 36V output ,so will the values of resistors change for different output?
Very good!
Thanks
Very Helpful ❤

which part have to change if I want LEDs to be less bright?
Thanks you

Thanks for your support...
I want to use 24 leds 2.5v each. Can i use same circuit??
Sir what value of capacitor used for 12 led
Is any tpye of fuse required for this circuit.... if required then which type
Nice explanation sir but how to calculate series resistor in this circuit?
That is not required. You can always use 300ohm to 600-ohm 1 watt.
Thanks
What size of fuse (mA) required if my output voltage is 200v (there are 15 led of 8mm in series)
Why is output voltage of bridge rectifier is not equal 1.414*Vac(24v)
How to make an led indicator for 220V AC?

Can you add motor in it
Where can i buy these components?
I have made the circuit but the output dc voltage is showing 56 volt where is my fault ????
isse ked bulb bana skte hai ?
how to make a 6volt secondary cell charging circuit transformer less
Why did you use 1M resistance; How it was calculated
It's a bleeding resistor. It is used to discharge the capacitor. It can be chosen randomly.
sir, i used ur circuit and apply to mini fan 24 volt, but suddenly my mini fan is burning and broken, can u answer this why.this happen.??..
Already mentioned in the video this circuit is only for small constant DC load. You can use load like LEDs. Not any DC motor or microcontroller.
What is the output current?

Pl upload charging circuit for Lithion ion 18650 auto cut off.
plz rply....12 led jalane k liye kya change hoga ?
No change required. Connect 12 leds in series instead of 8 leds
ok bro thanks....bt 0.22 uf ka capacitor nhi mil rha hai....
apse contact kse kare ..
👏👏
Thanks
@@TechStudyCell uploaded more videos brother yours explaination is too good 🙂
Sir ye kaise pata chalega ki out put load kitne amp ka hai
This power supply not for variable DC load. So you should know the aprox output current before designing the circuit

12 led k liye konsa capacitor use karu
0.22UF use karo
Formula for LED resistor is R = (Supply voltage - LED voltage) / LED ampere. So, R = (220-2)/0.02 = 11k but when I connect 11k with glass type transparent LED then it fuses after sometime. Why?
Because in your formula you have to multiply your 220 X square root of 2 to account for peak voltage.

How to make same this circuit only flash. ple can send circuit diagram.
Okay
12 led k liye kya kare
Make this for a arduino or ESP :D
