Electrical Engineering: Ch 7: Inductors (12 of 24) Inductors in Series

your videos are very helpful but I find that the thumbnails are misleading. also if it would be possible for you to do animated videos it might be a bit easier to read than the whiteboard. still enjoy your videos. thank you

Sir, Your videos are extremely helpful. Thanks for the amazing work you have done.

i like your voice

sir in my book i see that
in case of series aiding
L( total) = L1 + L2 +2M
And in case of series opposing
L (total) =L1 +L2 -2M
this book is consedring the effect of mutual inductance please explain am too confused ..

you can also change the currant by changing the magnetic field to current ratio. having a moving positive contact you can change the ratio thus controlling currant on an orderly fashion as the contact moves. taking the static to an active device changes everything you know about inductors.

Thanks you.

So why not just make it easy and say add them together

Real life, Vt= V1+V2+V3+IRsq+IRsq+IRsq, am I right or am I wrong...sq= squared?
