[SOLVED] Calculate values in a transformer

[Hatmpatn]

Yes!! I got it!

With input in matlab: -((12000*i*R)/(-12000*i - (16+15*i)*R+12000000*C*R))

Where the real part of the equation is:
R=1131.36*R+848520000*C*R+848520+1060.65*R

And the complex part:
C=848520+1060.65*R-1131.36*R-848520000*C*R-12000*R

We get R=171.788 Ω and C=8.40447*10^-6F

Which gives us when we put it into the equation: 70.71-70.71i

Congratulations!

Here's how I did it in Mathematica:

I just thought of something..

We want the equation to be =70.71-70.71j, but shouldnt it be =70.71+70.71j? In post #23 there was a positive sign but since that it was negative?

Remember the maximum power transfer theorem.

The impedance of the load must be the complex conjugate of the source impedance for maximum power transfer.

Yes ofcourse! Well, I'd like to thank you The Electrician for your help, and it was also pleasant to see that tony_lth got engaged!
