We can also call it an 'alternator', because it generates alternatingcurrent (AC).
我们可以也称之为'发电机',因为它产生交流电(AC)。

AcAlternatingcurrent (ac) is electric current that alternates between a positive maximum value and a negative maximum value at a characteristic frequency, usually 50 or 60 cycles per second (Hertz).
交流交流是指电流在正负最大值之间以特定的频率变动,通常频率为50或60赫兹。

If you have a fairly reliable and constant, high-volume flow of water then an AlternatingCurrent (AC) supply is a possibility.
