I love these videos, the graphics is so good these days. I wish I had access to info like this in my teens back in the 1970s.
All I had was ETI magazine, Practical Electronics and Hobby Electronics. Anybody remember Hobby Electronics??

I totally enjoyed this video. Simple and straightforward information.

i forget some of those things and making project 1 day ago and wonder how to calculate, you come in time to save me, ty for the great videos keep it up

[jacobmichael]

This video helps with a worksheet I had recently, thanks!

[Maharddhika]

What a great channel. May you be blessed with goodness.

[alancheng]

Thank you very much for your hard work, it taught me a lot.

[samuelmiller]

This is just the video I was looking for!

good video i was able to learn a bit, i got lost at the 2:48 power part because the current was not listed in the previous data sheet you put on the screen but it was ok.

Nice video. Anxiously awaiting manual subtitle upload.

My first semester of electronics school. The basics are important.

thank you Sir. subscribe is DONE and notification is ON

Very interested video.. I like discus about electronic componen t

[koronakorona]

is there a way of checking the parameters of the led when we are not sure?

[sierraalpha]

isn't 0.126 W should be converted to 1/8 W ? or is there something that i missed ?

no offense, this is what i want to know about these lamps. Thanks ;)

[leonidassotiropoulos]

Did you calculated only the resistor power consumption at the end of the video (whithout adding the LED consumption)? just asking i'm an amateur, but interested in arduino stuff .Great videos, very helpfull :)

I just have finished an extremely simple passive pedal. I have added this led circuit to it. Everything works, except when the led is powered and i engage the pedal, i experience extra hiss. Are there any options for filtering this unwanted added noise generated by the led circuit?

Question: Does the voltage drop equal to the required input voltage?
So for the example shown in the video with the 9V battery, could I just use a 2V battery with no resistor?
