A lossless transmission line having characteristic impedance Z₀ = 50  is driven by a source at the input end that consists of the series combination of a 10-V sinusoidal generator and a 50-resistor. The line is one-quarter wavelength long. At the other end of the line, a load impedance, Z_L = 50 − j50 Ω is attached.

(a) Evaluate the input impedance to the line seen by the voltage source-resistor combination;

(b) evaluate the power that is dissipated by the load;

(c) Evaluate the voltage amplitude that appears across the load.
