An 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 (rms) transmission value V to a much lower value that is safe and convenient for use in the factory. The transmission line resistance is R per cable, and the power of the generator is P. The generator can supply either Vt = V1 or Vt = V2. (a) What is the ratio of the voltage decrease AV along the transmission line when operating at V1 to the voltage decrease at V2? (b) What is the ratio of the power loss Pg at V, to the power loss at V2? Express your answers in terms of P, R, V1, and V2.
