😰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

[@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.

[@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.

[@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.

I want to reduce wattage of a 1000watt heater to 500watts. For that i want to add a resistor in series to heater. Can you confirn resistor value and wattage to be used to achieve this

[@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.

[@peeyushkansal6798]

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

[@anandanilkumar1238]

With 9volts battery connections we have got some 16milli amps current in the ckt . Will it be same 16milli amps in ac 220 volts, if not what would be the current?

[@TEKNOISTIX]

It will remain same That is the current requirement of led

[@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

[@supriyaandotra9451]

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

[@gharkaengineer6423]

I have a doubt sir, do we use the 437 ohm resistor to stop 7 volts from 9v battery and for 2v out put to the LED? Please clear me sir, i am not science student, but I have to know for my knowledge

[@arvindchim6763]

amanpreet sir can manage dc current by this divice when dc motor output is getting up to 1000 volt but we need only 60 volt dc motor and how to see output ampere of dc motor when we torque to motor and which divice i should use please tell me name

[@TEKNOISTIX]

To chek the current you can use multimeter in serious while setting multimeter knob on 10A point

[@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. ❤
