Transformer equivalent circuit shows that excitation current is just a tiny friction of the primary current. I always thought the pricinple of transformer was like this: voltage on the primary winding generates the current there, then flux in the core, then voltage on the secondary winding and current.
But obviously excitation current is not the same as the primary current and only the tiny part of primary current could generate the flux in the core. But I couldn't understand. Why can't the whole primary current generate the flux on the core since the whole winding is there?
Anyone can help me with this like I just got two candies from Santa in my company :)
