1.5D to 220v AC bit.ly/2xzzubL
in this video i have run a simple led with 220v AC directly and in 2nd project i have run RGB led with 220v AC
i have used just a resistor 56k a diode and a capacitor 100uf
other detial is given in the video
BAHOT HI LAZAWAB PROJECT 🙏
Use 68 or 100k to avoid burning led and stay safe because there is voltage flactuating by day and night
15k अच्छा काम chalta hain
May be 50K 1/2 or 1/4 watt
Per farlo bene occorre un piccolo condensatore ceramico da 400 Volt e 150 mf (anche più grande va bene tipo 400/600 mf), una resistenza da 680 Ohm 1/2 watt, in serie al condensatore e collegati al catodo del led, un diodo 1N4007 in parallelo sui poli del led con il catodo sul catodo e l'anodo sull'anodo del led per proteggerlo!
I 220 Volt della rete vanno sul polo libero del condensatore e sull'anodo del diodo...😉
Così funziona a meraviglia, non consuma nulla e non scalda. 👍
Enjoy...
I like that the LED is „Working propley“

Very best project thanks for you sir
For years I wanted to make one of these so that I get reminded of lights left on. But electronic stores like Jaycar stopped selling kids to stop people playing with high voltage. Even today such kids are hard to find. I used to see diagrams of Led being connected to Mains and I made a couple. That was in late 70s, when Dick Smiths electronics had stores all over Australia. Then the company decided to sell less components and more Appliances, radios/Tv's, and stuff other stores sold, leading to Dick Smiths going into liquidation. See what happens when companies start small and get too big? They will eventually go bankrupt.
if u connect 56k resistor to led and then directly to 220 AC, the resistor will burn
P= VI or P= V^2 /R for watt calculation of resistor
for resistor value V=IR
Resistor 56k / 3W oikota.
Bro then can we use voltage regulator for reduce volt?
Except, that never happens. It never burns and IDK why the math don't agree with the real-world example. Pretty much all the LED indicators (don't confuse with neon ones), have 47K - 56K or even a bit higher value resistor. I have seen manufacturers use 1/4th watt, gets hot for sure, but runs for years without any problem.
Hi, can you explain why the 56K resistor works? The math suggests putting 11K on 220VAC, or 17K assuming the peak voltage is 350VAC. But both the LED and the resistor burns when I put these values. I know that 47K and above works. 56K is quite good. But that's not what the math says.
What's wrong? Why the math don't agrees? What are the other variables to take into account in the math?
(230×√(2)÷0.005 ≈ 65K ( led should not constantly running it's max rated current ,.... 3.5 mm led ≈ 3-5 mili amp )
Edit- also should use a Diode for reverse voltage protection !!
Main---(50K or more)---(-LED+)--(+Diode-)---Main
(Sorry for any type error)
Which resistor is used for 8mm led in 220v..
What he is NOT mentioning is the 'Power of the Resistor'. There are 3 common Resistor Powers 0.25w, 0.5w, 1w. He is Using a 1w Resistor (From the physical Size).
Power Formula >> P=(V^2) / R
>> P= (240^2) / 56,000
>> P=1.03w
So You see, in order to meet the 1w rated power for the resistor, on '240v' , you need no less than 56k Ohm resistance.
Any Less, on 240v, and you will exceed the pwr limit and burn up the resistor.
Caution: It is not recomended to run a resistor at the limit of its power rating like shown in this vid. Use a resistor little 'More' than 56k for this application. You will get less Brightness, but it is safer.
O my dear Im not connecting 10v with directly
Current cross from diode and capicitor charge 10v then led flash and capacitor discharge
I prefer use two LEDs and a 100nF/400V capacitor. Little bit more expensive but much more efficient.
Cheers from Indonesia
Can U show me the Circuit Diagram ?
Do you mean the leds are in series or parallel?
in series

some people in comments are so stupid which is really unbelievable! And later someone wonders why there are accidents etc. People don't get anything of what is happening in this video!! This is really simple math like in primery school !! WTF is wrong with people these days!!??
बहुत अच्छा लगा वीडियो। दोस्त मुझे २ एम्पीयर का मोबाइल चार्जर बनाना सिखाए pls ❤️
mujhe ap ka vdo dekh ker bhut acha lala kya mai ba
Yes it works, but the resistor is heating up. This is only for intermittent use. For continuous use you need a higher wattage resistor
Use 1 watts resister sir
sorry, I'm a beginner... I want to ask if it's safe for a long time, for example for 12 hours, if you use a 10 volt capacitor for 220 volt AC electricity, thank you in advance, please provide guidance, good luck
Since it is a 220V, what about a 240V? What resistor does it need? And, doesn't it need a capacitor to stop flickering?
Nice project
Thanx sir
Hello, I want to use 20nos 5mm yellow color leds in series connect to 220v Ac. What amount resistor should I use?

If you have question Why 56k Resistor, Read on.

You said (but it is safer) .. do you mean that the chosen 56k ohm could short circuit or burn the resistor?
Which resistor value do you recommend?
The resistor got heated up in short time. Can you tell me it is a normal phenomena?
Because I'm going to use it for continuous application.
Very good. sir 5V 2A ki sply hai or 1 Watt ki smd led light hai kitne ohm ki resistor chahiye?

Good hobby to learn electronic better
thanx a lot dear plz visit my web for my promotions bit.ly/2w0TL5D
the first sample connects led with resistor only and no diode. does led work with ac current? is there a need for where the resistor side should be? (phase to positive for example)
LED will work without diode but it's life will be reduced. Diode is there for reverse current protection,because AC switches - and +ve. Wrong polarity on LED can damage if high current passes through it. Diode should be given on the - ve terminal of the LED and resistor to the +ve.
Muito legal. Parabéns meu jovem.
There is a mistake in the video and connection of the 1N4007 diode. You are showing with pink markings at the diode connection that ( - ) must be connected to the LED ( - ) but you are connecting the diode ( + ) to the LED ( - ). The silver line on diode 1N4007 is the cathode ( - ) ! Now where is the truth ?
thanx a lot for my encouragement

tinyurl.com/y4wzvbc5
Current flows in diode internally to the silver line direction, so the terminal of silver line always gives positive output. For this reason diode's -ve terminal(silver line) actually gives positive output and vice versa, and so here diode's +ve terminal connected to led -ve terminal.
Can we use only 56 k resistor for RGB?
Can we used higher values of resistor other than 56k resistor or it is the right computer value for that circuit?
Yes.. off course
You can try with 100k but you will get dim light.
Very nice and easy projects. Thanks

Ohh very nice
Without the led being connected the capacitor will charge to 310V dc and then blown to pieces.
Does it blow immediately if the led is faulty?
These practices are far away from my technical way of thinking.If something works it does not means that is also correct.
@@GeorgeGeorge-xj2bc The idea is to go /to working!
As I mentioned above, the guy (without using the capacitor in thousands of pieces ☺, let him talk!)
The idea would be. . . go? It works!
Go ahead ! ! !
Bună George !
Ideea e să meargă/funcționeze !

Ideea ar fi ... merge ? Merge !
Dă-i bătaie !!!
Acum 30 ani, cind am început a construi montaje electronice, un prieten de-al meu, avea o vorbă :
Atunci cînd un montaj îți merge din prima , are cel puțin 2 defecte !
- Un defect care îți face montajul "nefuncțional" ;
- și cel de al doilea defect, care îl anulează pe primul (un șunt).
@@GeorgeGeorge-xj2bc That small capacitor is rated at 16 volt 100 Microfarad.... It will pop up before charging to 310v

This is just going to electrocute someone or burn the place down. You're wasting energy but dissipating heat with the resistor which isn't up to the job. If this is going to be completely enclosed, use a small cap in series too... more more efficient then you can continue to use that wattage rating resistor.

These types of electronic assemblies are not trainings and especially very dangerous for apprentices. it would be more useful to explain how to calculate the resistance and use a low voltage supply.

THANKS ❤❤❤
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?
Same question. I know this trick to put 56K or higher ohm resistor in series to the LED since I was a 8 YO kid. But even after my graduation IDK why 56K+ works, while 11K burns both the LED and the resistor. Why doesn't the math agree with the real value? Heck, even if you calculate the maximum volt, that's 350VAC, it still calculates to 16K resistor. I think there must be something that should be taken into account in the math. But I don't know what.
@@SouravTechLabs But I came to know! Firstly, you were lucky that you were able to light up LED with 220v AC, because even I wanted to do that when I was a kid, but failed! Now, let me tell you that you can't even keep the LED glowing even with 56k resistor because even a 200k 1W resistor can't safely keep the LED glowing (especially the glass type BLUE or GREEN LEDs), but only RED one could survive (dimly). The reason is that LEDs are P & N type semiconductors and it doesn't behave like a resistive load with AC voltage. It's somewhat like capacitive and has negative phase power factor. As the resistor value formula of LED is valid only for DC, it cannot be used for AC. However, to resolve the issue, a diode should be used in series with the LED, in order to make the voltage behave like DC. Only after doing that the calculated resistor can be used with any LED. I have tested it and was anle to keep the LED glowing of any color without any problem!
@@debojitacharjee connect the diode in parallel in the opposite direction
@@monikanovotna7930 Doing that will burn the resistor. Where did you learn electronics?
@@debojitacharjee
Superb,but I have one doubt,,,,u r connect the Diode is reverse bias,,,,how it's possible
Yes sorry for wrong comments
Do resistor convert ac to dc, if not how led will glow
The resistor limits the current. The voltage across the LED is only a volt or two and the resistor keeps the current from being so high as to burn out the LED. Also, since the voltage across the LED goes across the capacitor and that voltage will be much less than the rated maximum voltage the capacitor can stand, it will be OK. Notice that the polarity of the capacitor is important also.
Although the LED is a diode and current will flow in only one direction, during the time the diode is off, the "reverse" voltage across the diode can be very high (it will be the peak voltage of the 220V AC signal - over 300V!) which would kill the LED. The "reverse" voltage across a diode can be only about 15 or 20V before it destroys the diode. The other diode is to block that super high reverse voltage from going across the LED and the little 10V capacitor.
This circuit would work with only the LED and a resistor except for the fact that the reverse breakdown voltage of the LED is too small. That is re reason for the big, black diode. Since the LED lights only on half of the AC cycle, it will flicker on and off at the power line frequency, and to make it worse, it will be on for only half of the AC cycle. The capacitor helps to reduce the 50 Hz (or 60Hz) flicker.
If you build this, please be very careful. 220V can kill you. And, when you wire it up, wear eye protection and I would suggest some gloves because if you hook things up wrong, it could get extremely hot extremely fast in your tinder fingers. Actually, a better recommendation is to use this example as a learning tool, work out the currents, voltages, power, etc. Understand what each diode does and why it is specified the way it was, then walk away and don't build it. For an inexperienced maker, this could go bad in a bad way.

I think it will be Brun with 56k resistance try 150k above resistance.
If you're using 1/4 Watts Resistor, it's definitely going to burn, however, 1 Watt 56k Resistor will survive ...
Ye resistance 56k Ka nehi yeh to 5.60k Ka he ..
Better use 2 number of 22k ohm, 2 watt resistor in series. With 3 Red 5mm LED in series. Diode also add.

Why RGB required diode, resistor and capacitor?
Because RGB need pure DC current

It is nice
Use half watt resister and 100 volts capacitor..and use it in consealed box with proper insulation to avoid hazard ous shock... An electronist
The single led bulb consumes less than half watt power. So half watt resister is sufficient. Since 56 k resistor is used to limit and control the flowing current 100 volts capacitor of even even 10 MFD is sufficient
