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

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.

Ultra-high voltages are used for electricity transmission to reduce current and minimize energy losses due to Joule heating. This method increases efficiency over long distances and is economically favorable for utility companies. Transformers help manage these high voltages for safe distribution to consumers.
