Ac generator provides emf to a resistive load in a remote factory over a two-cable transmission line. at the factory a step-down transformer reduces the voltage from its transmission-line value to a much lower value that is safe and convenient for use in the factory. the transmission line resistance is 0.3 w per cable, and the power of the generator is 250,000 w (rms).1 if (rms), what are

(a) the voltage drop dv across the transmission line,
(b) the rate at which energy is dissipated in the line as thermal energy?
(c) if instead were 8000 v (rms), what would be the voltage drop and power dissipated in the transmission line?
(d) repeat part c for (rms)
