GCSE Physics - Transformers and how they work

This shows the basics of a transformer and shows how they work. It proves the magnetic link between electricity and magnetism plus there is a little bit of magic ;-)
This covers electromagnetic induction, step up and step down transformers and shows how welders work.

Your teaching is so amazing.am now thing how to make my own transformer

[NA-petu]

this is the only video I actually understood this concept from!! thank you for the great explanations sir :)

This is a fantastic video sir well done

And of course, you either do not know or forgot to mention

*secondary current drops because of primary flux leakage and at the same time, secondary voltage drops because of secondary leakage flux*

Flux leakage leads to primary coil voltage and amperage phase shift. In other words, power factor of the primary coil determines output secondary power.

Note, *power factor of secondary is always one.*
