AC Power alternates direction and voltage, while DC Power flows in one direction with constant voltage.
AC Power vs. DC Power

Key Differences

AC Power, or Alternating Current, is characterized by its ability to change direction and voltage over time. This feature allows it to be transmitted over long distances with less energy loss. DC Power, or Direct Current, flows in only one direction and maintains a constant voltage, making it ideal for small electronic devices and battery-powered equipment.

In terms of usage, AC Power is the standard form of electricity for homes and businesses, delivered through power lines. It's easily converted to different voltages by transformers, enhancing its utility. DC Power, however, is commonly used in electronic devices like smartphones and laptops, as well as in automotive applications and renewable energy systems.
