Why your home's electricity constantly changes direction
In short: Understanding the fundamental difference between direct and alternating current is key to knowing how our world is powered. This video explains how electrons behave differently depending on whether they come from a battery or a mains supply.
Direct current (DC) is characterized by a steady flow of electrons in a single direction. This occurs when a circuit is powered by a cell or a battery. In contrast, alternating current (AC) involves a current that constantly changes direction, which is the standard for mains power supplies.
The video distinguishes these two types of electricity to show how they are utilized in different contexts, providing a foundational look at electrical physics.
