Alternating Current Transmission (AC transmission) is a method of delivering electrical energy over long distances using alternating current. In this system, the electric current periodically reverses direction, allowing for efficient energy transfer. AC transmission is preferred for long distances because it can easily be transformed to higher voltages, reducing energy loss during transmission. Transformers play a crucial role in AC transmission by stepping up the voltage for long-distance travel and stepping it down for safe use in homes and businesses. This process minimizes heat loss in the wires, making AC transmission a reliable and effective way to distribute electricity across vast areas.
