An ac generator provides emf to a resistive load in a distant factory over a two cable transmission line. At the factory a step down transformer reduces the voltage from its (rms) transmission value Vt, to a much lower value which is safe to use in the factory. The transmission line resistance is 0.30Ω/cable and the power of the generator is 250kW. If Vt = 80kV, what are the (a) voltage decrease ?V along the transmission line and the (b) rate Pd at which the energy is dissipated in the line as thermal energy? If Vt = 8.0kV, what are (c) ?V and (d) Pd ? if Vt = 0.80 kV what are (c) ?V and(d) Pd ?
