Alternating Current (AC) | 交流电

An electrical current that periodically reverses direction of electron flow. The rate a full cycle occurs in a given unit of time (generally a second), and is called the frequency of the current. The change in current is due to a change in voltage that occurs at the same frequency.

 

周期性地反转电子流动方向的电流。 一个完整周期的速率出现在一个给定的时间单位（通常是一秒），被称为电流的频率。 电流的变化是由于在相同频率下电压的变化所致。
