Inductance basics

The basics of inductance - how increased inductance creates a heavier filtering effect, and how coil windings and core materials affect the inductance of an inductor.

Love your videos, as always. I just have a few quick questions.

I have an old 'borrowed' phone charger in front of me with a bridge rectiIfier, a mess of capacitors, a voltage regulator and what looks like an inductor.

If capacitors and inductors are so similar in function, what's the point in having both? What's the difference?

Thanks, and I look forward to new videos. :-)

@Konflict42 Combine them into an LC filter and you get far more filtering than just one or the other.

I wish I could come up with a pun about inductors... Then my comment would be awesome.

[Afrotechmods]

@top2percent Me too.

sir, you are an absolute saint, keep up the good work, your getting me through college

Great video ..

For accurate inductance measurements at low values, I'd be wary of the one recommended in the comments (LC100). The one I purchased was VERY inaccurate below 30uH, and definitely not within the claimed 1% above 30uH..

Your videos are amazing! I don't know why I've been learning electrics at college for the past 2 months, I've learnt so much more on your videos in a couple hours! Makes great revision, thanks man.

Could you do a video on inductors used in generators, like the shake torch please? Im really interested in making my projects green so using a Faraday generator (an inductor with a magnet through it) is perfect! You have a way of explaining these things so brilliantly. I love watching them!

lol, nanohenry in italian sounds henry the dwarf haha. great videos, thanks for posting!

Thank you for posting this series of tutorials! I must say, you have an amazing ability for making the most abstract concepts as clear as a bell for thickheads like me, while still finding a way to make learning entertaining! Who says knowledge has to be boring? Well done, sir!

Capacitors smooth out voltage, Inductors smooth out current. This of course is simplified, but the basics are there...

love ur video..hope u can make a video about dc boost converter
