I have also made a video on led diwali light repairing
You can also watch that
@@TEKNOISTIX thanks for great help,,,,🙏🙏🙏🙏❤️
Knowledgeable video. Thanks
u cleanly cleared my all doubts.. thanks bro ♥️
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.
Nice... knowledge gaining tutorial.....tnx...on behalf of all electronic students...
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 useful information 👍 thank you
Super Excellent Teaching Sir...... Very well explained...🙏🙏🙏🙏
Thanks
Very good deep answer sir ji
Thanks for the tutorial. How does it afftects based on input current. let's say 5v and 2amp as input.
Presentation and information very nice. Ok
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. ❤
How ?
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
Good explanation
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 RUclips.
Thanks 😊
Same as you think.
We are the same
Agree 👍
Thank you for this video. But how to find out which wattage to be used for resistor.
Wah pa ji mast video h 👍👍👍
Very good way to explain basic concepts. Pl make video on LED bulb voltage, resistance according to wattage to understand calculations.
Thanks for appreciation 😊
I ll try to make video as per your suggestion.
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.
Great teaching sir,
very nice you are great
Thank you sir 😊
THANX WOH BHI SUPER
Wow! It's very simple and easy teacnike
Thanks 😊
Very nice vdo sir
Nice video sir
Very good sir thanks
👍🏻
100k resistance use kiya hai mene Red led ke sath ,
Extension box me as a Indicator,
Sahi chal rha hai
Chl jaye ga
Excellent guidance analysis
Sir ji kitane watt la resistor lagana hai bataya nahi
This is practical example. But do we calculate theorotically?
Calculate kiya to hai theoretical
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.
Already done
13k will definitely burn the circuit @ 220v. In real time people use 100k resistance with diode 4007. Kindly explain
💯right
U can try with 68k and a 4007 diode ...and a 10uf cap connecting at led legs with right polarity ..
22k to 47k is good for 220 v
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.
@@warrior7740 yes ❤
Good I formation sir ji.
آپ کی ویڈیو میں اواز بہت کام ہے
Nice video mate carryon good work
Amezing tutorial......
Sir please make one by one component and calculation withpractical........

Thanks for such knowledgable videos in your channel
I ll try
bro ager hum 3v led ko 220v postive ac k sath 4007 k sath postive dain to chalay ge
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. Very good
Sir, I have a problem, if you can help me, I will be greatful to you.
Sir, I have one smd mcpcb led plate which runs on 3 volt. (There are 10 smd leds on plate) But i want to use this mcpcb on 12 volt battery. How to use this? What resistance value can I use? Kindly guide me. Thank you.
It depends how much current your led's are consuming
Sir, how to check that led's are consuming how much current.
I have shown the method in this video
Very nice sir
Beautiful ❤️
ur great teacher
Veerji mujhe 5mm ki 14 LED ko ek sath direct AC power supply se chalana hai to kaise connect kre pls bataye
Sir kisi b circuit main fusible resister ki value kaise calculate karen koi formula bataen
Sir, if we connect an led to 220v with 20k ohm resistor then the resistor will burn... Because we need some high watt resistor..
Yes you can calculate the wattage with formula P=V*I
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
Make video on SNUBBER CIRCUIT❤
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.
10% up ya down koi bhi le sakte ho
Sir, thanks, how resister helpful? What if we directly connect to battery
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
@@TEKNOISTIX I watched many channels.. But u explain the way we want.. Thanks
Sir plzz make videos on use of CRO , LCR meters, and other important electronic equipments
thanks bro ♥
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.
+Amol Bagul if you having led of 1.8v and the voltage source of 1.8v you don't need any resistance
Phaji bohat badiya
Thanks
Sir AC ko 24v DC me convert krna hai without Transformer to kon se diode ka use kre value kaise calculate kre is per vedio bna do
Transformerless power supply ka video hai 1 channel pe
Usme 7805 ki jagh 7824 laga do
24 volt aa jaye ga
Phaji mai ek device nu chalana hai AC to DC mai thodi vedio dekh lyi mai nu samaj aa gyi but mere device 24V DC and 12A te operat honda hai 24V te mai creat kr la ga but 12A mai kida generate kra ga eh daso
24 v 12 amp layi thonu dedicated supply laini paye gi
Without transformer nahi bane gi eh
Sir resistance ka Watt kese nikala jate hai plz uske bare me ek tutorial plz ?
Sir i have only o/p voltage and i/p voltage then how to calculate current and resistance by ohm's law
Ghaint sir ji
Thanks
Great 👍
Thsnks
very good
well explain
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.
Super video sri
Sir if we have 12v baatery and 3 v. LED but don't know about ampare .No multimeter . Then how we would calculate Amp.on papers .of exact calculatin of resistance .?
But sir ac current me polarity ni hoti to ye led to polar hoti hai, Phir kaise glow hogi,
This LED wil blink on ac very fast
sir aap multivibrator circuit ke bare mei bataiye Ki isme transistor ke saath capacitor aur resistence ek saath Kaise kaam karte hai aur kis tarike se kaam karta hai.
Okay
very good explanation.
Thanks 😊
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
To chek the current you can use multimeter in serious while setting multimeter knob on 10A point

Sir I want to drive 25W LED panel from a step down transformer with ac 25v . After rectification the voltage rises up to 33 VDC what value of resistance should I use
Can u please explain with circuit digram.
How to deal with variable current? Which resistor to use? Like current fluctuate between 3v to 5v
