Inductor basics - What is an inductor? 

There is something wrong with your measurements. At time 1:44 the current waveform should be showing a time constant and "rounding" of the leading edge as well as the trailing edge as shown to be occuring. The waveform should be symmetric. This is really strange. It seems you are using an oscilloscope to read the voltage across the resistor to get the current but your waveform is not right. How did you do this? GH

we are a manufactuer for inductors components, i wonder if you have interesting? thanks.

where the fuck did you go to school

Same. $30,000 / year university vs 3:53 minute youtube video.

YumYumOrYuck, sounds like Trump university you went to.

Sounds like you were in an arts course.

Only if you would have paid attention in school..

It helped that he stated exactly what inductors do right at the beginning. Store electrical energy in the form of magnetic fields.

Yess

Thanks bud!

I know this is a two years old comment. I have nothing against this channel except for thanking them. But to be honest with you. Its not about how great of a teacher he was. Its all about how much attention you're paying to what he said. Watching a video seems to be the best method to attract your attention thus allowing you to absorbed the information without any disruption or disturbance(if that even a word). I've observed that many people would instantly understand a topic if they were to search an explanation over at youtube or internet. This perhaps because of your willingness to pay attention. At school, You are most likely forcing yourself to understand which has backfire on your memory instead of absorbing information you have block your memory for you have no interest in learning.

@@mandingo4698 primarily because of replay button imo

@@narutouzumakix9201 YEA! And I can go back 5 seconds when I needed to :D

Same issue here. I'm glad these people take their time to help those in need.

serious: can you explain or describe your learning disability? I am genuinely curious about how something like that can come about, and how specifically having such a disability hinders your ability to learn? thanks.

megamanxu I'm at the bottom of the class no matter how hard I study. I sometimes bang my head on the wall during exam week. Some of my classmates at high school have a bad hobby of cutting classes and sometimes drunk but they still got better grades than I do and I never cut classes. I live in a developing country and although I never been evaluated by a doctor and diagnosed with learning disability but I know that I must have some learning disability by comparing myself to my classmates.

bobskie321 Electronics classes in many schools are mainly taught with giving the students the theory of how things work and then they can apply that learned theory to experiemental labs. It has been done that way for decades. For a lot of people, they eventually learn the abstract concepts by rote memorization while filling in gaps of practical knowledge with labs and later throughout their career. For others, leaning these multiple abstract concepts is just too much. There is nothing concrete for their minds to figure out and they go into a hopeless tailspin of despair thinking they are somehow broken because the other students get it. Nothing can be further from the truth. First, you just learn differently. Nothing bad about that. Second, most students don't even grasp the significance of what they are learning until 2 or 3 years later down the road, but they are fortunate enough to be able to memorize so they can get through the tests. You can learn this stuff, and you are by your own admission. Quit selling yourself short and seek out more remote learning outlets (like these videos) for your learning. I'd also suggest a few self learning books on electronics as well. Eventually, your brain will have enough practical knowledge that the theory will start making sense. And even if it doesn't, there are plenty of people in the work force that know how to apply real world practical skills without knowing the background theory. Just know where you can apply those skills and where you can't. Best of Luck to you - and keep on trying!! :)

bobskie321 just start learning from d basic..every line u read of d book just keep asking your self why m doing this untill n unless u get d satisfactory answer ...nd when u got it..go to d next line n do d same thing... nd u will rock..good luck dont give a damn to grades,, ur knowledge nd understanding is much more imp. good luck with that :)

It's because the magnetic field around the wire, adds up, when coiled into an inductor, this is what produces the back EMF

yeah, i think so. thanks.

maybe this is design engineer can get it.
