AC is easier to transmit over long distances, can be transformed to different voltages, is cheaper to distribute, and works well with electric motors. It is widely used in homes and industries for these reasons.

Alternating Current (AC) offers several advantages over Direct Current (DC), making it the preferred choice for power generation and distribution. One of its key benefits is the ability to transmit electricity over long distances with minimal energy loss by stepping up the voltage using transformers. AC systems are more cost-effective and easier to maintain, especially in large-scale power networks. They support the use of efficient electric motors and are widely compatible with household and industrial devices. Additionally, AC can be easily generated using alternators and allows for simple voltage regulation and control.
