Answer Details

The main reason why a.c. (alternating current) is transmitted at very high voltage and low current is to reduce the amount of energy lost during transmission. When electricity is transmitted over long distances, some of the energy is lost as heat due to the resistance of the wires. This is known as power loss, and it can be reduced by increasing the voltage of the electricity. By increasing the voltage and decreasing the current, the amount of power loss is reduced because less energy is lost as heat due to the resistance of the wires. Additionally, high voltage a.c. can be stepped down to lower voltages, making it safer for use in homes and businesses. Therefore, transmitting a.c. at very high voltage and low current is more efficient, cost-effective, and reduces heat loss during transmission.
