The Significance of Alternating Current (AC)
Alternating current is electricity that periodically reverses direction, unlike direct current (DC) which flows in only one direction. AC’s advantages are significant:
| Feature | Alternating Current (AC) | Direct Current (DC) |
|---|---|---|
| Transmission | Efficient over long distances | Inefficient over long distances |
| Voltage | Easily transformed | Difficult to transform |
| Applications | Power grids, appliances | Batteries, electronics |
The ability to easily transform voltage allows AC to be transmitted over long distances with minimal energy loss, making it the ideal choice for powering homes and businesses.
