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.

@shashanknaik755 9 месяцев назад

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.

Aap ye bataiye ki operating voltage ke according resistance ko kaise calculate kr ke lgaye LED me.

@singhsaketanand 2 года назад

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.

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.

@ChristopherDsouza1 2 года назад

1 K Ohm.

@Dave_en Год назад

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.

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. 😢
