Calculating Current Through Compensation Winding in Cascade Voltage Transformer

[track]

Got cascade voltage transformer made from two completely identical units.
On secondary winding, load takes I₂=1A
Number of compensation and secondary windings is equal.
I need to find current trough compensation winding I_c .
θ₁ = θ₂
--> θ₁ = I₁N₁ + I_cN_c - I₂N₂

--> θ₂ = I₁N₁ - I_cN_c

--> I₂N₂ = 2I_cN_c

--> N_c = N₂

--> I_c = I₂ /2

--> I_c = 0.5 AI did it like this and get feedback that this is wrong without explanation. So, I would be grateful if someone can explain me what is wrong here. I can post scheme if needed.
Thanks in advance.

Can you post a diagram labelling things? And what is theta?

I found this is correct solution, so no need to torture you any moore.

*Theta is electrical flow. If you are interested, I'll sent you sheme.
