Hey I am new to y oi ur channel, Thanks for the video they have help me alot keep up with your content.

[@TheVonMatrices]

I think it's worth pointing out that you want to put as many LEDs in series as possible before going in parallel. That way, you can use smaller resistors and have less energy wasted in resistors (thus longer battery life).

[@jonathanm9436]

Also good to know.

[@travarious2810]

Good call. Thank you

[@aquila1919]

Only if you are using standard LEDs on something like a breadboard, so that they are easy to replace. If one breaks, none of them will work if they are in series, so this might not be the best solution if they are not easy to replace

I believe at 4:23 the resistor power is 0.41976W, say 0.42W. Not 0.49W as stated. Not that it matters as the same half Watt resistor would be used. Thanks for your video as I am new to LED's and I am making my own head tracking setup for DCS.

[@airmanfloyd719]

@@EngineeringMindset I have a question because I'm trying to understand more about how current flows. What's the result if something conductive touches just a hot line, hot-neutral, and hot-ground?

[@djrj0]

@@airmanfloyd719 when the circuit encounters a low-resistance path between electric potentials, the current through the circuit will spike into the hundreds of amperes. This will generate a lot of heat very quickly, and will either cause one of the wires to melt, or one of the circuit elements to destroy itself violently, such as a battery.

I have a parallel LED circuit with two LEDs, a green and a red. They both have a resistor (that I believe is the correct value for the individual LEDs) and the red LED has a switch on it. When I turn the switch on the green LED dims when the red LED lights up.

[@TheAnimeist]

1:25 Should be: Battery Life = 500 mAh / 120mA Later on you have the equation correct. Not being picky, just trying to help improve on an already top notch and practical explanation of LEDs.

You shouldn't connect LED's in parallel like at 3:20 as a failure could cascade and cause them all to burn out

Hi can I put 90 leds in parallel on a 12v mains adapter please

[@watnoudan]

Thanks for making this video! Im confused though... the setup at 1:50 has 6V in each branch. But you have 6 branches. Does that not "strain" the power supply? To me it seems im asking for 6V 6 times...

[@cadillacescalade5428]

Hi, I am trying to use 6 led red flashing leds they are 20 MA at 2.0volts I am wanting to use them on a 12volt DC on a bridge for train layout

[@Joh750]

You state resistor power. I am wondering if that resistor power is the same power from power supply for my LEDS. I would like to setup 20 white LEDS in parallel. Your example has a 0.49W. Therefore I resume I would a power supply that can provide at least 0.50w

[@tedlahm5740]

[@Vihen-fw1wl]

Can we use copper wire for red wire and blk wire

[@sjsaranlal23]

🎉🎉

[@Cornish_Co]

It should be noted that color LEDs which are in clear plastic when off require different supply voltage. However, LEDs that use colored plastic to filter the light are typically the same voltage. You should always check the manufacturers cut sheet for the correct voltage and drive current.

[@gamingwithlambo1750]

1:30 will the brightness of led decreases or remain same

[@svem1972]

Could you plz do one video on battery level indicator for 3.7v and 12v. People use different resistance values connect in parallel with leds to indicate battery voltage. As per your lecture if take same colour led of 3mm connected in parallel with 3 leds would like to glow when full if battery is 100% if battery reach to 50% then two leds if battery reaches to 20% then cut off. Let's assume battery 18650 full is 4.2v Then let's set another volt for 50% that means when battery reaches to 3.6v and when reaches to 20% means 3.2 and when battery drain to 3v complete off. So here would like to understand calculation of resistance use in circuit. Please help. I am leaning and interested to apply such circuits

[@atzuras]

if you calculate a 1/2 Watt resistor you may want to use a 1W instead to keep it cool and safe.

2:02 Why wouldn't the current per branch increase in your calculation for the resistor when you did take that into account in your later explanation with three LEDs in parallel but with one resistor before they branch out?

[@russell2952]

I'm repairing a parralel/series lighting circuit. It's 18V, with 7 parallel sets of 4 LEDs (28 LEDs total), each branch having one 73Ω resistor. What a disaster. Anything goes wrong with an LED and either that branch all fails, or in the case of a short, the current spikes on the others and they burn out. There's no constant current control for when anything happens to a single LED. The design is EXACTLY as you describe in this video and it's horrible. The math all makes sense until an LED misbehaves and then it's cascading failures. I'm rebuilding it as individual LEDs in parallel.
