b.shahvir said:Assume ideal conditions i.e. zero winding impedances in pri and sec. Also assume load or burden impedance to be zero. The sec will draw infinite amps, ideally! So, what will happen to core flux in this case? Will it increase, decrease, remain constant or disappear (become zero) altogether? The reply would be interesting!
Well, I suppose it depends on what ideal is, but with 100% coupling and no leakage, infinite current in the both coils will result in no flux in the core. Doesn't transformer design theory tell us this? The only way flux actually builds up in the core is when a voltage starts to appear across the coil right? Since the flux in the core is what indirectly causes the reactance then if we say infinite current this implies zero reactance. I know it may sound like I am contradicting myself but it really isn't a contradiction.
