Electromagnetism:
A transmission line has a characteristic impedance Z0 = 50 Ω and attenuation 3 dB/100m (α = 0.345 Np/100m). Assume that the velocity factor is 1.0 (i.e. the propagation speed along the line is equal to the speed of light). The line is 500 m long and a load resistance, RL = 50 Ω is connected to one end of the line. A sinusoidal voltage source is connected to the line at the other end, with a peak voltage of 10 V.
How much power does the sinusoidal voltage source deliver into the line?
How much power is dissipated in the 50 Ω load resistance?
What is the RMS voltage (note – not the peak voltage) measured over the 50 Ω load resistance?
