Too good explation

Is emf essentially the same as potential difference?

Well explained sir, I'm satisfied with your teaching👍🏻❤

I love that how he explains everything practically and it makes so much more sense which makes it easy to understand❤

You don't know in India 220 v comes.

Good

Gemmm❤

greattttttttttttttttttttttttttt explanation !!!! Bravo

Sir but current increases on decreasing the voltage
That means microwave needed less current than charging mobile

Why not use a potentiometer to vary voltage instead of transformer?

Thankyou ❤

Need to get to the point.

This is literally the best lecture on tranformers, great explanantion all doubts cleared. Most of the other videos I found were mostly just definition and formula based due to which I couldn't actually get their working.

Thankyou sir

the best thing about this educator is how he bulids things up slowly amnd genuienly taeches us the importance of every component
