The best explanation and tutorial for beginners and advance levels.

[@hanyelbanna3673]

Wonderful explanation 👏 Bravo 👏 Go on May Allah bless you ❤

[@ShotgunRumble]

dude this is awesome! after looking at a few other videos and knowing a little about the calculations, this video was exactly everything I needed for my led project!

[@SL-Tourist]

Excellent explanation.Thank you

[@sonnybeau8560]

Good teacher 👏🏾

[@GodwinOAkoma]

Fantastic illustration 👍

[@mychannel8672]

Thanks for giving so much of idea or knowledge on this subject. Really in fact i was totally i had no idea. Though there is lots more to know in this vast sea of knowledge. Thank you once again.

[@rineshboilla1608]

How to check led voltage and current with multimeter practically one video

[@mohamedanees1313]

Very clearly understand. Thanks bro

[@hotbird3]

This was confusing to me for 20 years , thank you so much for this easy and beautiful presentation 👍👊

[@user-ir8fs7ss2l]

Excellent video, very well explained. And due to your presentation, you have earned a new subscription. Keep up the good work and thank you.

[@venkatn4399]

Hi...! Nice explanation and appreciate your video. I have a small doubt. If 2V and 4V LED's are connected in series, we were using a resistor. But, the resistor only limits 3volts and allows 6Volts to pass through the 2V LED. In this case, the 2V LED will get damaged. How to overcome this...?

[@samconomo3726]

Great video. Thanks

[@Hk_Network127]

Great Bhai ❤

[@bashiruosman473]

Excellent lecturer. God bless you and increase your knowledge.

[@mydjsir]

loved the way you explained LED resistance basics!!!!

[@rolanddejesus8685]

thank you very much sir..

[@bharatkumarindian]

One and only video on this topic

[@mkamalakkannan8327]

Very good.

[@bhavinsitapara5156]

Vary nice video

[@timgroleau1612]

Well done. Love the step by step. Mystery solved.

[@balakotireddy7006]

Your videos are very neat explanation.Thank you..

[@mamidivasudev5988]

Superb explanation thank you.. please make a details fulll video like the how to use multimeter to check all components

[@saikatdutta1991]

Nice explanation

[@FardousKarimSifat]

Just awsm

[@naijarobotves5951]

Wow very nice video

[@mcsrecordingstudioalbionvi5082]

Liked it, great explanation :)

[@ryanpersaud3100]

Thank you. Very helpful

[@abdyldemiri1544]

Very good video thank you

[@KhinMaungTun-q9u]

Thanks a lot.

[@michaelnjogu8833]

Wonderful lecture

[@petersketch1990]

If you change battery though how many ohms it need ?

[@am1manTravel]

I presume it doesn't make any difference if the resistor is close to the LED or maybe a couple of feet away close to the power source. ????

[@jetbob309]

Friends i very like this video

[@ceciliapatrick7766]

Thanks Sir: Very well explained ,no doubt at all. Now I can tryout practically. Can I use same formula with any Model phone charger ? Is it safe? Thanks once again for explaining so well, with examples. Well done God bless you and all your efforts.

[@SABARI-nv9kf]

Sir, i have seen a big circuit ( they have using series of Resistors , capacitor instead of single what is concepts behind that)

[@MithileshKushawaha-on2xy]

Good method

[@sushantkadam644]

Suppose I have a 20 volt source and need a 15 volt output....so how can I calculate the resistance for this circuit?

[@subhamoykundu2997]

Thanks sir

[@natureslittlegifts]

So if its 0.14 watt output on red led I would be able to use a 1/4 (0.25) watt resistor.

[@ff-mu6cc]

cool!

[@OMGFacts00]

what if vL is greater than Vs. means 6v se toh 10 leds bhi jala sakte hai na.ye to possible hai he.

[@OMGFacts00]

yaar konsa software use kia

[@filmonYaci]

Amazing

[@seenivasanseenivasan6685]

Super

[@laijugeorgh6348]

👍👍👍

[@meowmeowclubart1879]

QUESTION, WHAT IF 10 3MM LED LIGHT IN 1 BATTERY 9V IN A ROW WHAT RESISTOR DO I USE? OR SHOULD USE 390 OHMS 10 RESISTOR EQUIVALENT TO 10 LED LIGHT I MEAN 1 RESISTOR PAIR LED LIGHT? IN ORDER TO FIT 1 BATTERY 9 VOLT? WHAT HAPPEN IF WE DONT USE RESITOR? HOW MANY LED LIGHT CAN BE LIGHT UP? :)

[@rudranil3608]

where can I get the datasheet

[@md.sowmik7944]

If there are more bulbs, VL = 2v+4v+2v+3v = 11v. And VS=9v. So, voltage drop = 9v-11v= -2v. Here is the negative value. Ultimately result will be negative. Then what will be the calculation???? I have to consider this negative value as a positive???????????????????

[@nisaulkamila1816]

what if we use a battery with 27V and 9 lamps, each have 3V, in series, do we need to use resistor?

[@GameXArt12]

No

[@GameXArt12]

Because if you use a 9 led in series and each led use 3v we multiply 9x3 =27 If you use parallel we have to attach an resistor because current is flowing constant and each led use it separately and does not act like a blockage like in series FOR further info say IJ in the reply

[@alisaqlainqureshi]

How we'll know the value of current?

[@TheElectricalGuy]

You have to check the datasheet of the device or measure the current by using Ammeter

[@SquareTVBox]

I got 389 ohm
