Una linea transporta energia electrica al regimen de 5x10^4 kw desde su origen ( planta hidroelectrica) hasta la ciudad donde se consume. La ciudad esta a 50km y la linea tiene un resistencia de 0.004 Ω por km. A) Hallar la perdida de potencia electrica en la linea, si la d. d.p. entre ambos conductores es: i) 10^5 v, ii)10^4 v, iii)10^3 v, iv)110 voltio

Ibelieve that the correct answer is: c. along plate boundaries

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.

What does the start look like
