Hi
I wondered if anyone could explain as to how actually the whole process of transformation
of voltage happens. I know the equations involved but can't get them together to reach a conclusion.
When a.c. is passed throught the primary, a flux is induced in the core, which travels to the secondary, and induces an emf in the coil. Now emf induced is higher, I understand, because number of turns are more. But why is current lower. I know the ratio equation, but I wanted an explanation as to how actually increase in voltage leads to the decrease in current.
I may sound a bit silly, but the problem is that I know what happens to emf and current separately, but am unable to connect the two things together.
