Vahelduskorrel
Vahelduskorrel, also known as *alternating current* in English, refers to an electrical current that periodically reverses direction, unlike direct current (DC), which flows in a single direction. This phenomenon is fundamental in electrical engineering and power distribution systems, enabling efficient transmission of electricity over long distances.
The alternating current waveform is typically sinusoidal, characterized by its frequency, measured in hertz (Hz), and
One of the key advantages of alternating current is its ability to be easily transformed to different
Alternating current is generated by rotating machinery, such as generators, where a coil of wire spins within
In contrast to direct current, which is used in batteries and some electronic devices, alternating current
