Textbook Question
Chapter 10, Problem 10.12P
In a circuit in which a sinusoidal voltage source drives its internal impedance in series with a load impedance, maximum power transfer to the load occurs when the source and load impedances form a complex conjugate pair. Suppose the source (with its internal impedance) now drives a complex load of impedance ZL = RL +XL that has been moved to the end of a lossless transmission line of length
