3 मिनट तो वैसे ही टाइम वेस्ट कर दिया भाई जो काम की बात होती है वो फटाफट बताया करो ना एक ही बात बार बोल रहे । अब बताता हूं अब बताता हूं करके 3 मिनट कर दिया
For english speakers, Let me simply tell you this for 1 and more leds. Find out how much voltage your led runs in. Mostly it is 2.9 or 3 Volt. And Find out the current, mostly it is 20 mili amp. Now you're using a 5V supply: In this 5V you need to drop 2V to get 3V because 3V is rated Voltage of your led. Formula Goes: V = IR Put in the values 3 = 0.02 (currrent in amp) times R So for 5V and single LED, R is 150 ohms. Find out the resistors you have for the closest value. Now for two LEDs, if you connect them in series then they would need 6V and a 5V supply cant supply 6V without some Boost Converter. But eff that we gonna use parallel In parallel, currents adds up and voltage remains same. So current is now 40mA for 2 LEDs Voltage drop needed is still 2V to get 3V from 5V supply. V=IR 3=0.04 times R R= 75ohm. You can add more LEDs in parallel as long as the power supply can handle those Current ratings in Amp. You can't tell I'm right because you need less resistance for more energy to flow to power more LEDs.
For calculate resistor value:- Vs-Vl R = ---- I Vs= source voltage (input voltage) Vl= Load voltage (LED operating voltage) I= load current ( led current rating ) Put all values in formula and calculate you will get resistor value. For calculate resistor watt:- W=Vd×I Vd= voltage drop I=Current (LED current rating) (Vd= source or input voltage - load voltage )-> this one is for calculate the voltage drop NOTE : -when calculate the resistor value and watt current (load current) value should be in ampere. If current rating is in mA then convert it into Amps and calculate.

V=IR, LED ki operating voltage 2volt se 3 volt hoti hai, matlab isse jyada voltage denge tab LED damage ho jayegi. Formula: Resistor = (Battery Voltage - LED voltage) / desired LED current. For a typical white LED that requires 10mA, powered by 12V the values are: (12-3.4)/.010=860 ohms. To use several LEDs in parallel, sum the current values. From the example above, if we use 5 white LEDs the current requirement is 10mA x 5 = 50mA. So (12-3.4)/.050=172 ohms.
Kindly make a video for beginners on how to select a diode for dc to dc input voltage current etc. This thing is tricky. I've made a dc to dc 1.5 to 37v variable motor speed controller using LM317 but the transistor gets damn hot despite of using heat sink. I'm recommended to use a 3amp diode but I don't know what does it mean by 3amp diode. 😢
Bade bhai jankari achhi hai, lekin seethi calculation bataye ki LED kitna current leta hai aur voltage across LED Kitna hai to koi bhi easily calculate kar lega jaisa ki formula V=IR agar LED ka current aur voltage drop pata, ho to baki kitna, drop karana hai resistance calculate ho jayega Exam. Volage across LED 5 VOLTS , current 1mA CHALANA HAI 220 VOLTS PAR to seethe Se 215 drop ke liye V=215=1mA*R , yani R=215/1mA=215K
sir ji , mai apka video dekhkta hu bhothi use full hai , mera ek problem hai jo ki 5 mm rgb led ka zaler ko 70 se 80 led lagaya hai , to zaler me konsa fuse resistance lagana hai ? aur kitne lagane hai? cirkit out put 312 volt dc hai hai
Button led ko agar 12 v me jalaye toh bina garam hoke pura bright dene ke liye kya karna parega...?ho sake toh aap button led ka details video banake samjha dete to atcha hota..

I have 2 out put one is 2 volt one is 3 volt I want to used only 3 volt led when we are connected 2 voltage input supply 3 volt indicator should not blowing kindly suggest
I have UV led whose specifications are : Max forward current : 20mA; Max reverse current : 50mA Max forward voltage : 3.2V - 3.4V Max power dissipation : 80mw Max reverse voltage : 5V What value of resistor is needed to glow if the Battery input is 12V 9ah. Kindly reply.
Dont see too many specs. Take LED voltage as 3.3 volt as average, 20mA max (15mA actual assumption). 12 volt as source. You get 12-3.3=8.7 volt across the resistor. Divide by 15mA, 8.7/0.015=580 ohm. Take nearest value available. 620 ohm will be best choice. You can use even 1kOhm if you are okay with nearly half brightness and current of 8.7mA.

बहुत अच्छा तरीका बताया आपके मार्ग दर्शन से हम कभी असफल नही होंगे धन्यवाद सर जी असैही व्हिडिओ बनाये हम आपके आभारी है धन्यवाद
बहुत हि काम का विडीओ बनाया दोस्त
For calculate resistor value:-
Vs-Vl
R = ----
I
Vs= source voltage (input voltage)
Vl= Load voltage (LED operating voltage)
I= load current ( led current rating )
Put all values in formula and calculate you will get resistor value.
For calculate resistor watt:-
W=Vd×I
Vd= voltage drop
I=Current (LED current rating)
(Vd= source or input voltage - load voltage )-> this one is for calculate the voltage drop
NOTE : -when calculate the resistor value and watt current (load current) value should be in ampere. If current rating is in mA then convert it into Amps and calculate.

Hatsoff to your experience.... पहले calculation के साथ बताइए। और उसके बाद आपका experience.... धन्यवाद। आपका वीडियो अच्छा है।
You should talk abt calculation rather than different value

Yes, calculation is more customised. These are generally accepted values which do work. Knowledge Vs belief.🤣🤣🤣

Ye 5 volt led को ac ya dc दोनो सप्लाई से work करा सकतें हैं रेजिस्टेंस लगा के या ac LED अलग होता है और DC LED अलग होता है

I have UV led whose specifications are :
Max forward current : 20mA;
Max reverse current : 50mA
Max forward voltage : 3.2V - 3.4V
Max power dissipation : 80mw
Max reverse voltage : 5V
What value of resistor is needed to glow if the Battery input is 12V 9ah.
Kindly reply.
1 K Ohm.
Dont see too many specs. Take LED voltage as 3.3 volt as average, 20mA max (15mA actual assumption). 12 volt as source. You get 12-3.3=8.7 volt across the resistor. Divide by 15mA, 8.7/0.015=580 ohm. Take nearest value available. 620 ohm will be best choice. You can use even 1kOhm if you are okay with nearly half brightness and current of 8.7mA.

Bhai 5 volt supply hay constant 5 volt deti hay or 3 watt ki led hay to konsa resistor use karna chahiyay
Achha kaam kiya

Teach the calculation how you can selected the resistor for led
Red LED 5mm ki series me 12 volt se jalana hai 3 ya 4 LED jodkar PN+PN+PN+PN KON SE RESISTANCE LAGANA PADEGI PLEASE BATAYE
