    that was one of the best videos I watched in this subject. I have some questions;
    wattage of curcuit or for a specific resistor should be considered? for 5v supply, 1w 3v led, the wattage for resistor is not 1w?? because the 0.3 apms from led in 3 volts is under 1w.
    another question is can we run a 6v led on 5v usb supply? is it be on max brightness or even lighted up?
    if we want a 1w resistor 56 ohms, can we use 4 1/4 14 ohms resistors in series?

      Lovely video content! Excuse me for butting in, I would love your thoughts. Have you thought about - Runayslarn Survival Manifestation (do a google search)? It is a good exclusive guide for discovering how to repair your electronic items without the hard work. Ive heard some incredible things about it and my work buddy finally got excellent success with it.

    So, why then, when I connected 10K 0.25W resistor to the 12V battery it got hot enough to burn my finger? According to the calculations: 12v/10000 Ohms = 0.006Amps; And then 0.006A*12V = 0.072Watts. While resistor tested was 0.25W - way more then 0.072Watts required. Why is it getting melting hot?

    100 ohm resistor of what watt should be used to convert 5v to 3v?

    • @ralphbooger4756
      @ralphbooger4756 3 года назад +1

      5v power supply, 100 ohm resistor, 3v led gets 0.02a.
      5v - 3v = 2v
      2v / 100 ohm = 0.02a
      2v x 0.02a = 0.04w
      general rule is that the watts used should be less than half of the rated watt of the resistor!
      1/4 watt resistor 0.25w / 2 = 0.125w max can be used.
      1/8 watt resistor 0.125w / 2 = 0.0625w max can be used.
      so you can use 1/4 and even a 1/8 watt resistor since your setup only use 0.0400w.
      i think... im new at this, if it blows up dont blame me!

    • @christiannielsen3863
      @christiannielsen3863 3 года назад

      217 volt x 0,02 A = 4,34 watt
      217 volt / 0,02 A = 10.850 ohm
      Given the LED diode use 20 mA.

    • @ralphbooger4756
      @ralphbooger4756 3 года назад

      it would be bad practice to use one resistor for 20 leds, if one or more of the leds die then the math changes... also as a rule the used watts should never be more than half of the rated watts of the resistor!
      and if you was to have a resistor for every led, you would need one 1/2w resistors or two 1/4w resistors in parallel for each led.
