# Need help with this transformer circuit

I need some help with this circuit. I have simplified it in three steps. The task is to find the current I. The values to e(t), Z1, Z2, Z3, Z4, and the turn ration N1/N2 are known. I'm not quite sure if I have even done the transformer conversion correctly. But my main question is the current I.

Z4 = Z1 + Z3
