The principal disadvantage of sending electric power across country on very low voltage transmission lines would be
A) the wires need to be too thick and heavy.
B) high current would cause significant power loss.
C) the low voltage can leak out, leaving none at the end.
D) they would interfere with each other too much

Question

Quizplus · Accepted Answer

High current in low voltage transmission lines leads to significant power loss due to the resistance in the wires. This is described by Joule's law, where the power loss is proportional to the square of the current.
