Why is it economical to use extremely high voltages for the transmission of electrical power? High voltage and lower current implies that the electricity can travel longer distances. High voltage and lower current implies that the wires used can be thinner. High voltage and lower current implies that the power loss (ohmic heating) due to resistance is low as well. High voltage and lower current implies that the power plant can generate electricity more easily. High voltage and lower current implies that the resistance is higher, leading to a smaller power loss. High voltage and lower current implies that the amount of power generated per minute is very high, therefore rendering the method very efficient
