The best explanation and tutorial for beginners and advance levels.
This was confusing to me for 20 years , thank you so much for this easy and beautiful presentation 👍👊
loved the way you explained LED resistance basics!!!!
Excellent lecturer.
God bless you and increase your knowledge.
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.
Your videos are very neat explanation.Thank you..
Well done. Love the step by step. Mystery solved.
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.
One and only video on this topic
Superb explanation thank you.. please make a details fulll video like the how to use multimeter to check all components
Thanks sir
Thank you. Very helpful
Very good video thank you
Wonderful lecture
Thanks a lot.
Good method
Amazing
Super
yaar konsa software use kia
Sir, i have seen a big circuit ( they have using series of Resistors , capacitor instead of single what is concepts behind that)
So if its 0.14 watt output on red led I would be able to use a 1/4 (0.25) watt resistor.
👍👍👍
where can I get the datasheet
what if vL is greater than Vs. means 6v se toh 10 leds bhi jala sakte hai na.ye to possible hai he.
what if we use a battery with 27V and 9 lamps, each have 3V, in series, do we need to use resistor?
No
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
How we'll know the value of current?
You have to check the datasheet of the device or measure the current by using Ammeter
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? :)
I got 389 ohm
