Exercise 17

A generator with an open-circuit voltage v g ( t )= 10 sin 8000 t (V) and internal impedance Z g = 40 + j 30 (Ω ) is connected to a 50-(Ω ) distortionless line. The line has a resistance of 0.5 ( Ω/m), and its lossy dielectric medium has a loss tangent of 0.18%. The line is 50 (m) long and is terminated in a matched load. Find (a) the instantaneous expressions for the voltage and current at an arbitrary location on the line, (b) the instantaneous expressions for the voltage and current at the load, and (c) the average power transmitted to the load.
