very good job sir

nice explained so very good

Very intresting .and calclation of capacitor isuseful .you have explained in simple way...thk you

Bahut achha laga. Jaisa capasitor ka valur nikalna dikhaya main line me jo laga hua ha woisa hi agar aap resistance jahan jahan laga hua hai usika value niklna jadi dikhate too accha hota.

Nice problem solve ❤😊

Thank Bhai video banane ke liye

good video

Very deeply explained..With calculation. Thanks a lot sir...

Very informative 👍👍👍

Very good information and calculation 👍🙏

Very very nice information apriciate

Awesome video, Simple and best

Very well explained 👍

मान लिया सर U R Great

Nice vedio 👌👌

Thank you sir

Nicely explained

Nice

from BANGLADESH , excellent explain , thanks for the video .

Good. Information

Nice Explanation. Thank u very much.

I like video

Great..

Thanks sir

Thankyou

Good sir g

Excelent excelent excelent explanation

Awesome

Nice amazing

Sir aise hi calculate kar video banay taki hum bhi calcuate karna sikhe aur components k formula ko bhi samjhayen. thanks sir

You have covered almost whole information about transformerless power supply

V good

Would a 100volt 3,700 or 5,000 or 10,000 Farrad capacitor be dangerous ? I need 100volt because a bicycle bottle or hub dynamo can output up to around 100 volts ac on very fast down hill descents. I plan to use it to make a full wave bridge rectifier as a smoother for my vintage bicycle dynamo lights to stop the very annoying strobing that occurs with the AC & to hopefully enable the light to glow for a few minutes when stopped at traffic lights when the current from the dynamo is no longer flowing - the capacitor discharging into the load ( a 3 watt total of front & rear led bulbs). How long could I expect the lights to glow for before going out completely with these value capacitors please?

pl. make video of led tester .

what value capacitor needs for 12v 1Amp output

Sir, explained very good but you have not explained about value calculation of electrolyte capacitor. Please explain, and I want to your notification. Regards, Chanchal Bepari

You have used 230v for calculation which is RMS Value *NOTE* WE HAVE TO USE MAX VOLTAGE WHICH IS 230*√2= 325V

Can we use 473k400v

Sir what watt resistors u hav used? Can I use 1/2 watt resistors?

Sir, 104/105 j 400 vt use kar sakte hai kya LED light (1w/3w)

50 watt ka mcpc banana hay kon sa sa spare parts lagega vallu bataiye sir.

What is the condition of voltage and current in series & parallel connection of LED

Nice explaination. Sir, polar capacitor ka aur resister ka calaculation kaise kare iska bhi video bana do.

sir elctrolytic capacitor micro frade kese calculations krte h plz explaion

Sir 47 uf 63 v capacitor ki jagah konsa lgaa skte hai

Thank you but Can I use this circuit to charge three acid batteries 4V in a series to LEDs strip lighting !!?? if yes; Does this circuit cut off when the batteries is full !! ??

Bhai mujay 12 volt k card main lagnay wali relay chlani hai please batayen kon sa capator lagay ga 1 m k resetance k sath

correct me if im wrong, the main reason for using this capacitor is to drop voltage, so why cant we use resistor instead of capacitor? and basic working priciple of a capacitor is to store charge so how its working here to drop voltage?

how to calculcate all component values. I understand theory and selection of X rated capacitor. pls answer

Ssr ji rajitens ka wat bta diya karo kitne wat ka lagegs

If we do not put load that is any led. Will the circuit get damaged if we plug it in 230 ac

Motorcycle ac head light led convert. How to do??

pf k saath kon sa candansar lagana chahey

How to find the current?

What you are taking as 220 V, should be 220x1.732 which is approximately 311 V for calculation.

128 volt polarised capacitor ka uf kitna hoga

Ur connect 20 leds are series or parallal

sir.dopper.circuit.may.fillter.capaciter.ka.calculion.nahi..kiya.usper.ak video.banaya.sir

Sir led ka ic ko kaise direact karu

It's a useful video. I have few questions. (1) Why is draining capacitor charge required? (2) Can having a polar capacitor in the output reduce light flickering? Also, can you please also create a video on how to create a homemade (1) regulated power supply and (2) isolated power supply for LED light? Thanks a lot.

Maine 474 j aur 63 volt 100uf ka capacitor lagaya tha 9 watt led bub ko. usme 1 watt ka 15 led laga huva hay , dim glow ho rahy kya kare?

1 M Ohms ke resistor ka wattage kya hoga?

Drain out resistor ki value kaise calculate kre

Sir give answer of comments

4.796

can you help me

@02:13 this symbol of an inductor. Resistor symbol is different.

सर youtube के कुछ वीडियो में led driver में fuse resistance के जगह पर Nutral or Line के port में 4 diode लगा कर जला रहे है क्या ऐसा हो सकता है

Sir 24 volt ke liye konsa pf lrna hoga?????

10 to the power 6,ye kaha se aaya sir?

What it the LEDs are in parallel?

Resistance ki Watt to bataya hi nhi

In case of led series light/jhalar why 100 ohm resistance required and how to calculate that ? Someone said 2.2 ohm 1w is enough so I want to know that calculation also. Also, how to calculate bridge rectifier's electrolytic capacitor value( here there is not any second pf but an electrolytic capacitor) ? If u give a video explaining all this then it would be very informative

Thanks for nicely explaining. I have two forward questions. 1). If I want to light 72 odd LED's consuming all 230 v, should there be any requirement of the Capacitor ? 2) In that case what shall be the current flow ? How to control and fix this at 25 mA ?

Sir Mera blue smd led strip hai jiska 1led ka vf 3.8v aur total 92leds hai to kul voltage 349 ho raha hai aage mujhe nahi as raha please reply.

कृपया हमें बताने का कष्ट करें कि आउटपुट में कितने माइक्रो फेरेट का कैपी सीटर कर लगाया जाए

Sir meri tv ka 100uf 16v capisitor kharab hogya mere pass do capisitor hai kaon sa lgaye 220uf 16v ya 100uf 25v

Why this LED bulbs are blinking ?

This circuit in put 80v to 400v

120 ka r kyu?? Parallel capacitor ka capacitance kitna??

100 watt possible

Very scratchy background piano sound.

Hmye itni math nhi aati hai bhai koi shortcut smja sako to samjao plz

How to calculate electrolyte capacitor value which is used in bridge

Sorry sir itni maths batai ye Hamari smj M nhi aai Hmye math nhi aati jyada .Direct esa koi formula ho to bataye smj sktye H

😭😭me samja nahi

Your calculations is wrong. You have avoided Max. Value ( PIC. Value) of Input AC. You have mentioned here RMS value. As a result of as per your calculation the dropper capacitor will be damaged.

पता नही क्या समजाया???? लप म लप म हो गया और... पहली पांच मिनट तो टाइम बर्बाद करने वाला ही है।
