Explain why ultra-high voltages are
used to carry electricity over transmission lines.




Sagot :

Well, let's take it the other way. If you have a rather low voltage (220 volts -- Europe -- is low) you'd get a high current, which more easily dissipates as heat, resulting in loss of energy. Using a high voltage you have a low current which could easily be transported with almost no loss.
