How to Calculate Resistance Required for LED

[@Mr.Nitin1999]

😰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

[@sivanparvathisankaran1046]

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

[@OrnatePixels]

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. ❤

[@roseelectronics4582]

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 KZbin.

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.

[@TEKNOISTIX]

Already done

[@peeyushkansal6798]

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

[@rajeshkumrpshah]

Good explanation

[@edgarcordova4534]

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 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

[@J.GowriPrasad1970]

Generally many people are using 100k resistor to make 220v ac LED indicator. You are showing a resistor of about 13k according to the calculations in your video. So I don't understand what is correct. So please clear my doubt.

[@vijaybendre250]

Great teaching sir,

[@anontoakanda5847]

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

[@TEKNOISTIX]

Yes you can calculate the wattage with formula P=V*I

[@rajnitalwar8035]

very nice you are great

[@vikashkumar_le908_nwd5]

Sir, thanks, how resister helpful? What if we directly connect to battery

[@TEKNOISTIX]

Usually led operates on about 2-3 volt if you use a 2 or 3 volt battery you can connect the led directly For higher voltages resistance is added for protection

[@Niru-gd3yc]

@@TEKNOISTIX I watched many channels.. But u explain the way we want.. Thanks

[@kingsingh9367]

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

[@harshalpalaskar2593]

💯right

[@subhajitchakraborty951]

U can try with 68k and a 4007 diode ...and a 10uf cap connecting at led legs with right polarity ..

[@anitajaved3467]

22k to 47k is good for 220 v

[@warrior7740]

100k Resistance use only for safty. Because 2-3v led light is a dc base bulb not for ac voltage. But true circuit calculation showed in this video. I hope you understood this.

Hello Friend, Thank you for this calculation. Question - If I have 1.8V input Voltage, then How would I calculate Resistance? as I have seen LEDs with operating voltage (VL) 1.8V. agar min voltage to turn ON the LED is 1.8V. Toh usko kaise select kare? This case is when I wants to select LED as well as resistance. I only have 1.8V input voltage.. Please guide.

[@TEKNOISTIX]

+Amol Bagul if you having led of 1.8v and the voltage source of 1.8v you don't need any resistance

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

[@techrama9642]

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.
