How To Run Mini Led In 3v 5v 8v 12v 18v 24v 220v Using Resistor Youtube Step 1: the web way. the easiest way is to use one of the online calculators provided below. just click on one and enter the info from the previous step and you're set! you only need to go to one. the led center (for single leds) the led center (for arrays of leds) led calculator (for single or arrays of leds). If you need parts, try led load resistors (usa) ebay.us m8pkfzled load resistors (uk) ebay.us urd203led load resistors (aus).
Wiring Leds With Resistors What value resistor for each led should we use? v s = 9v; v f = 2v; i = .02a; r = (9 2) .02 = 350Ω. a 350Ω resistor is also not one of the standard or common values so you can jump to a 390Ω or 470Ω resistor instead. by using a power source with a lot more voltage than what the leds need, we have to compensate by using a larger value. Twist the silver part of the red wire on your coin cell holder to the silver part of the red wire on your led. twist firmly (3 or 4 twists are suggested) to make sure you have a good connection. repeat this with the black wire from the battery pack, attaching it to the green or black wire of the chip led. 4. Step 1: 3 volt basic led circuit with 10 ohms resistor. the above diagram shows a 3v led circuit, in this circuit there are two aa cells are used. when you are operating an led with 3v you have to use minimum 10 ohms resistor . for more details visit simple basic led circuit. All other colors of led lights and led light kits sold at evan designs need a resistor to run at 3 volts. at 5 12 volts and 7 19 volts, all mini leds need a specific resistor with a specific ohm value to protect the led against too much current which will destroy the led. the resistor used is based on a calculation using maximum operating.

For this second setup i decided to use the same led, but up my power supply to the three aa batteries wired together which output 4.5v enough power to burn out my 1.7v led, so i would have to use a resistor. to figure out which resistor to use i used the formula: r = (v1 v2) i where: v1 = power supply voltage v2 = led voltage. R = (15v 2v) .020a. the voltage value needs to be what is left over after the led's needs. in this case, our maximum voltage is 15v because it is from a vehicle. the led requires 2v, so that will leave us with 13v in excess. the led uses 20ma, which is the same as .020 amps. the formula works when you use amps.
