váltóárammal
Váltóáram, often abbreviated as AC (Alternating Current), is an electric current which periodically reverses direction and changes its magnitude continuously with time, in contrast to direct current (DC) which flows only in one direction. The waveform of AC is typically sinusoidal, meaning the voltage and current vary according to a sine wave. This sinusoidal nature is crucial for efficient transmission of electricity over long distances.
The primary advantage of AC over DC for power transmission lies in the ease with which its
Key characteristics of AC include its frequency, measured in Hertz (Hz), which represents the number of complete
