Final answer:
Long-distance power transmission requires stepping up voltage using transformers to minimize power loss and transmit efficiently over vast distances.
Explanation:
In long-distance power transmission, voltage must be stepped-up using a transformer to increase the voltage for efficient delivery over hundreds of kilometers while minimizing power loss.
Transformers play a crucial role in this process by increasing the voltage at the power plant using a step-up transformer, which reduces current proportionally for transmission over long distances.
This step-up in voltage, often to levels like 330,000 volts, allows for power to be efficiently transmitted to consumers over long distances before being reduced to safer levels for use in homes and businesses through step-down transformers.
