Hello,
I'm really struggling to understand this one simple thing, would be great if someone could help me:
Given is a simple circuit that consists of a generator and a load. The generator's internal resistance is \(Z_G = (20 + j30)\Omega\), the load \(Z_L = (40 - j30)\Omega\).
I understand that I have to transform one of them to achieve \(Z_L = Z_G*\). According to the sample solution, I am supposed to add an LC circuit to achieve that. Why can't I use a simple parallel resistor? According to the solution, it is impossible to reduce an impedance's real part by adding passive elements. I don't know if I'm missing something really simple here, but why it that? Isn't that exactly what you do when adding a parallel resistor?
