Ur video is very useful 😃👍
Love the vids
Hey I am new to y oi ur channel, Thanks for the video they have help me alot keep up with your content.
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).
Also good to know.
Good call. Thank you
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
Check out NEW resistor video, everything covered! ➡️ ua-cam.com/video/DYcLFHgVCn0/v-deo.html
@@EngineeringMindset but resistor still draw currrent how would It make battery life longer?
so thankful for these electrical knowledge you are throwing at us.
- big fan of your channel
I hope one of your next videos will be on designing switch mode control for LED, or maybe LED matrix, and analysing how its used to significantly increase efficiency and reduce power loss. Keep up good work. Best regards.
Awesome video still! Planning on doing some crafting stuff with LEDS and didn't know where to start, this video helped so much cleanly and plainly explain it withough going into any jargon. Thanks so much!
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. A couple of bucks in parts, an old webcam and free software is going to save me a lot of money .Your video has helped a lot.
Regards,
IKM

Hey Paul, amazing job 👍 My students ask one more question: Do you have a video tutorial how temperature regulation works in HVAC (especially on mini split AC) systems..? if yes, we couldn't find about it on your channel 😒🤔
We have covered this a little in our PLC video ua-cam.com/video/uOtdWHMKhnw/v-deo.html but I'm writing a script as we speak for HVAC basic controls. Should be ready in ~2weeks
@@EngineeringMindset amazing, wish every success 👍👍👍👍
@@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?
@@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.
Excellent. Step by step and exceptionally clear, aided by simple and clear graphics. Bookmarked. Thanks.
Thanks for explain the ohm's law
I learn more from this channel thanks for your hard work😉😊
Other than ohm's law,i think you have to understand about Kirchoff's Voltage law and Kirchoff's current law as well.To be able to analyze your circuit.Like this LED video example.
@@yojanna1237 yeah ok
Truly, I cannot thank you enough for such a concise and well put together explanation. ✌️😑
Excellent. I was just looking for these calculations. Thank you very much for the video.
Thank God I finally got the answer I was looking for. Thank you for this video
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.
It's really helpful for me .
I need it so much.
Thanks " the team "
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.
👌👏👏👏👏👏👏👏👏👏👍🙏🙏
You're an excellent and honest instructor 💐
You are working hard for your each videos . Soon you will reach 2 million. All the best 👌👌👍👍❤
Its Very helpful to get understand easy way. Keep going.
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.
yo literally before a moment I noticed that too
Well spotted
Very nice explanation!
Great content as always. Big salute to you.
Thanks for a brilliant educational video.
You shouldn't connect LED's in parallel like at 3:20 as a failure could cascade and cause them all to burn out
Thanks paul👍🏾 paul right?😅 Anyways, thanks for the videos, I've been thinking how to connect led for a week now and burn almost a hundred of em bc didn't match voltage and resistor 🤦🏾♂️ so this video is really helpful bc i would like to build a led vu meter for speaker so this is really helpful, its easy to buy pnp but i would like to do it myself 😅
gosh it worked thx so much
ur videos are amazing
thank you for the great lecture, pls make a video also for ir receiver
Your information is good, thank you
if you calculate a 1/2 Watt resistor you may want to use a 1W instead to keep it cool and safe.
Check out NEW resistor video, everything covered! ➡️ ua-cam.com/video/DYcLFHgVCn0/v-deo.html
This 5 minutes worth my time
thank you so much for making this video :)
A tremendous amount to absorb (math) in one video. As usual, Thank You.
This is like 3 projects in my circuits class combined in 1 video lol
Thanks so much for the amazing content
Thanks
Vids frequently!
Thank you
1:30 will the brightness of led decreases or remain same
Please make a video about Operational amplifiers
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.
Very nice!
Great,as always 👍🇬🇧
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...
If all kinds of LED color need 20mA,that means if we want to use different color of led with the same supply,constant current method is better than constant voltage method,Right?
Awesome, I burnt out so many LED's as a kid it was not funny.
Make a video about Synchronous motor
Hello My question is, If a Drone is flying at height so does its rotor or motor gets affected by lightning in rainy season.
How come current doesnt increase in each branch in the second example? Wouldnt it need to draw 60mA each branch now?
Where did you get the 0.02A value from? My LEDs have a Voltage value and some other value of 3 to the right of what looks like a p with the line swishing through the centre and flicking up. What is it? Ohms, Watts, Amps or something else?
Super
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?

Thanks 😊
☕🥃😎👍🏻
Help! I'm looking for a clear explanation on how to wire multiple bulbs to one switch in Europe. Can't find anything!! Do you have one?
Wire them in parallel
Thanks… I understand, it's the different coloured wires/switches that are confusing me, every search brings up 2 or 3 way switch wiring or for US
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
Can we use copper wire for red wire and blk wire
SUPER 👌👌👌👌👌👌
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
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
if i use a current regulator, can i connect different color led in parallel? and for the voltage? if i get for example 3.5V for all color?
Seen the new LED explained video? so much detail covered! ua-cam.com/video/O8M2z2hIbag/v-deo.html
Hey is there any other platform I can buy your shirts/ hoodies from ? Spring shipping is kind of lengthy
Hi can I put 90 leds in parallel on a 12v mains adapter please
How to work CRT television?
make this video & upload your channel please...🙂
An LED bulb is actually just a regular bulb. Both still have a filament in them
0,02 Amp is the maximum power rating for the LEDs ....
Can we run 100 led connected parallel or serious vy one led driver . The drive will take ac input 230v. Pr we need to put resistor for ech led. Plz answer

Can anyone tell me why I can't get get leds to light up in a parallel circuit on my breadboard? Is the current just taking the path of least resistance and ignoring the led?
See our LED circuit design video

Prosto, jak krowie na rowie, wytłumaczone tak że nawet bez znajomości języka każdy kumaty wie co ma zrobić. Straight, like a cow in a ditch, explained so that even without knowing the language, every "kumaty" knows what to do.
permission to study sir
👍
what is 0.02A..
Read datasheet.
20 milliamperes
Ok so you mean I've got to seperate all the LEDs I have and then calculate their power to get a resistor and then use them to make my 9th class science project 😅😅
9 volts + 3 volt LED = Burnout or explosion!
Hi. Please check your email. I have sent you something I belive you would be interested in. I would love to hear back from you.
