växelströmstillförsel
Växelströmstillförsel, often abbreviated as AC supply, refers to the method of delivering electrical power using alternating current. In this system, the direction of the electric current reverses periodically. This is in contrast to direct current (DC) supply, where the current flows in only one direction. Växelströmstillförsel is the standard for power distribution grids worldwide due to its advantages in voltage transformation.
The fundamental principle behind AC supply is the alternating nature of voltage and current. This oscillation
A key advantage of AC supply is the ease with which its voltage can be stepped up
Common AC voltage levels for residential use vary by region, often being around 230 volts in Europe
