Alternating current is transmitted across large distances at high voltage to minimize what?

Alternating current (AC) is transmitted across large distances at high voltage to minimize power loss due to resistance in the transmission lines. By increasing the voltage, the current flow is reduced for the same amount of power transmitted, which significantly decreases the I²R losses (where I is current and R is resistance). This allows for more efficient long-distance energy transfer and reduces the need for additional infrastructure.
