Vekselstrømsbaserede

Vekselstrømsbaserede refers to systems or devices that operate using alternating current (AC). Alternating current is an electric current that periodically reverses direction and changes its magnitude continuously with time, in contrast to direct current (DC) which flows only in one direction. This characteristic makes AC particularly well-suited for long-distance power transmission due to the ease with which its voltage can be increased or decreased using transformers.

The widespread adoption of AC systems, largely driven by the work of Nikola Tesla and George Westinghouse, has revolutionized electrical power distribution. Most household and industrial power outlets provide alternating current, typically at a standard frequency such as 50 Hz or 60 Hz depending on the region. This means the direction of current flow reverses fifty or sixty times every second.

Electrical grids are fundamentally vekselstrømsbaserede, utilizing AC for generation, transmission, and distribution. While many electronic devices require DC for their internal circuitry, they incorporate rectifiers to convert the incoming AC to DC. Conversely, some specialized applications, like certain types of electric motors or specific industrial processes, might directly utilize AC. The versatility and efficiency of AC power systems have made them the backbone of modern electrical infrastructure worldwide.
