How to Calculate Resistance Required for LED 

😰सर ऐसे प्रैक्टिकल नॉलेज की हमारे शिक्षा व्यवस्था में बहुत जरूरत है। 12th क्लास वो शिक्षक सिर्फ बस थिओरी ही पढाता था, वो फिलिंग ही नहीं आती थी. EXCELLENT AND MARVELLOUS EXPLANATION. LOVE FROM MAHARASHTRA

great Sir! Love from neighbour`s land! buhut acha samjhaya.

समझाने का तरीका इससे अच्छा हो ही नहीं सकता 🙏🙏🙏🙏🙏🙏🙏

Sir ji aap ke video bahut achche lagte hain aap jo bhi explain karte ho ek hi bar me samajh aa jata hai pls esehi continue kijiye

video boht acha hay....... AC and DC key liey resistor ki calculations apnay bata di hay...... thanks...

The world's best teacher you have really helped me alot may Almighty God reward you

Very very good and useful presentation for learners thanks

Amazing knowledgeable video sir ji👍👍👍👍👍✌✌✌✌

Very very useful tutorial video 👌 Thank You Sir ❤️

very nice you are great

Nice video sir

Very nice vdo sir

Bohut se video dekhe magar itna simple aur easy koi bhi nahi hai. Thank you 🙏 Resistor ka watt calculate kaise karen, ispar bhi video post karen.

Great very great explanation is so good in hindi

Such an amazing and easy way to teach this topic to the new beginners. You are the best teacher

Good explanation..... easy to understand......

Thank you very much Sir for detailed explanation It's very useful for me

u cleanly cleared my all doubts.. thanks bro ♥️

Best calculation method with practical

Very very helpful bcoz i am reparing my old diwali liting but it burn every time i don't know why then i watch' your video then i realise my mistek i,,,, thanks for making this video,,,🙏

Very good way to explanation and praticaly done. Nice sirji

Hi you did ohms formula with sincere and great effort to understand the ordinary people, well done &hearty congratulations

Very very good presentation good explain thanks

THANX WOH BHI SUPER

Nice... knowledge gaining tutorial.....tnx...on behalf of all electronic students...

Thank you sir 😊

Knowledgeable video. Thanks

Sat sir akkaal ji Your teaching is very nice 👏👍👌❤

Super Excellent Teaching Sir...... Very well explained...🙏🙏🙏🙏

Nice video mate carryon good work

Use full video sir thank q

Pranam 🙏🏼

Thank you for this great tutorial! I knew quite well how to calculate current limiting resistance for LEDs before watching this. However, I usually watch the same content over and over again to solidify my understanding. I also feel that learning from different sources always adds fine bits of knowledge to my repertoire. The whole point of this is that I don't watch mediocre videos. I always watch the best on RU-vid.

Good I formation sir ji.

Thanks so mach dear friend god आपका बताया है वह करने का मन हैं सामन लिए वक्त का कारण है कहते गाडी चेले लेट पहुंचा गी जगह पर लिखा है क्या बताया जायेगा श्रद्धा सबूरी धैर्यवान इंसान का है

Very good step by step explanation. Please do mention wattage calculations in conjunction with the resistance, as both go hand in hand for successful operation of the circuit.

I subscribed your video bcz nobody explain same like you .only color code and connection .l watched many videos. which resister need for a supply and how will it find out In this video you describes step by step thank you so much pls give reply for every person'sdoubt

Very nice sir

thanks bro ♥

Wow! It's very simple and easy teacnike

Phaji bohat badiya

Great teaching sir,

Super video sri

Very good deep answer sir ji

Thank you for this video. But how to find out which wattage to be used for resistor.

Ghaint sir ji

Very good way to explain basic concepts. Pl make video on LED bulb voltage, resistance according to wattage to understand calculations.

Great 👍

Excellent guidance analysis

Your theory and calculations are absolutely correct, but using a 13 kilo ohms resistor at 220 volts will burn out the LED, Because at that time not 16 milliampere- more than 200 milliampere current is flowing in the circuit. ❤

Beautiful ❤️

very good

ur great teacher

Thanks for the tutorial. How does it afftects based on input current. let's say 5v and 2amp as input.

You are logical and always helpful. Keep it up. Also make a video for a night light (not bulb) with the help of a LED and explain in the same nice and clear way as you always do. Bless you.

Very good sir thanks

آپ کی ویڈیو میں اواز بہت کام ہے

well explain

Yes, LEDs light up based upon the current flowing through them. Use ohm's law to calculate the resistance on a given voltage in which it is to be used and the power formula to calculate the resistor wattage so that the resistor wattage should not be less than the calculated wattage of the circuit. If to be used in AC, parallel another LED or rectifier diode in reverse bias as a reverse voltage protection.

Thanks sir.

13k will definitely burn the circuit @ 220v. In real time people use 100k resistance with diode 4007. Kindly explain

Sir ji kitane watt la resistor lagana hai bataya nahi

Amezing tutorial...... Sir please make one by one component and calculation withpractical........ Like TRANSISTOR CAPACITOR INDUCTOR VARISTOR LDR DIODE Thanks for such knowledgable videos in your channel

very good explanation.

awsome sir 😍 thxx

Thank you

100k resistance use kiya hai mene Red led ke sath , Extension box me as a Indicator, Sahi chal rha hai

Sir jee thankyou fothis led resitance calculation but plz share your earlier videos regarding diffrnt typed rectifiers and their operation both 1 & 3 phasr rectifiers

Sir plzz make videos on use of CRO , LCR meters, and other important electronic equipments

Thx sir g❤

This is practical example. But do we calculate theorotically?

Sir resistance ka Watt kese nikala jate hai plz uske bare me ek tutorial plz ?

Fine.

But sir ac current me polarity ni hoti to ye led to polar hoti hai, Phir kaise glow hogi,

Nice

Thanks

Make video on SNUBBER CIRCUIT❤

Sir kisi b circuit main fusible resister ki value kaise calculate karen koi formula bataen

great

bro ager hum 3v led ko 220v postive ac k sath 4007 k sath postive dain to chalay ge

Well done

Veerji mujhe 5mm ki 14 LED ko ek sath direct AC power supply se chalana hai to kaise connect kre pls bataye

👌👌👌👌👌👌

Ok sir i practicl with 1k resistor the Voltage Drop was 1.99V and current passing through LED was 7.9mA with 220ohm Voltage drop 1.85 volt and current was 30mA With 700K the Voltage drop was 1.55Volt current was 3 micro Ampere. This method is good to find voltage drop but Current varry according to resistor hence Data sheet would be better.

Sir, if we connect an led to 220v with 20k ohm resistor then the resistor will burn... Because we need some high watt resistor..

15 k with 1N4007 ke dwara 1LED 240v ac me 3day tak jalata hun.. achcha e to jalte hain ji..

Iam like your english title

great video, but resistor power wattage should be considered, especially in 220V AC situation, (safety margins)✔

Sir ye calculation karke ko jo resistance aata h . market me wo exact available nhi hone pe uska nearest value wala resistor lena chahiye matlab us value ka resistor se kuch jyada hi hona chahiye na ❓ Please give answer sir. please clear confusion.

Thanks sir g, 🙏🙏🙏🙏🙏

How to deal with variable current? Which resistor to use? Like current fluctuate between 3v to 5v
