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 t to a much lower value that is safe and convenient for use in the factory. The transmission line resistance is 0.30Ω/cable, and the power of the generator is 250 kW. If V t = 80kV what are

(a) The voltage decrease AV along the transmission line and

(b) The rate P d at which energy is dissipated in the line as thermal energy? If V 1 = 8.0 kV what are

(c) Δ f and

(d) P d? If V t = 0.80kY what are

(e) ΔV and

(f) P d?
