Maximum Power Transfer for Z = 12+24 Ohms

[andytb1232000]

Homework Statement

Find the required value of the load to achieve maximum power transfer for Z = 12+24 ohms

Homework Equations

ZL = Zs

3. The Attempt at a Solution [/b

As the question does not state whether or not the phase or magnitude of the load can or cannot be varied. I believe the answer to be ZL= 12-24 ie the complex conjugate.
Does this seem correct?
