Vaihtojännitteita
Vaihtojännitteitä, also known as alternating current (AC) voltages, are electrical potentials that periodically reverse direction. This type of electrical current is commonly used in power distribution systems due to its efficiency in long-distance transmission. AC voltages are generated by alternating current generators, which convert mechanical energy into electrical energy by rotating a coil in a magnetic field. The frequency of AC voltage is typically measured in Hertz (Hz), with the standard frequency in many countries being 50 Hz or 60 Hz.
The primary advantage of AC voltage is its ability to be easily transformed to different voltage levels
Vaihtojännitteitä are used in a wide range of applications, including residential, commercial, and industrial power supply.
