Alternating Current vs. Direct Current

Alternating Current (AC) and Direct Current (DC) are two types of electrical flow. AC changes direction periodically, meaning the voltage flows back and forth, like the current in household outlets. This allows it to be transmitted over long distances efficiently. In contrast, DC flows in one steady direction, like the power from batteries. While AC is commonly used for powering homes and businesses, DC is often used for charging batteries and electronic devices. Each type has its advantages, depending on the application, but both are essential for modern technology and infrastructure.
