This is an alternating current generator. 这是一台交流发电机。
Besides voltage, resistance and capacitance, an alternating current is also influenced by inductance. 除了电压、电阻和电容之外,交流电(AC)还受电感的影响。
Nicola Tesla invents alternating current. 尼古拉特斯拉发明了交流电(AC)。
The method includes the following steps : exerting alternating current on the coil to generate an alternating magnetic field; 该方法包括对线圈施加交流电(AC)以产生交变磁场;
This high frequency alternating current produces the high frequency radio waves mentioned in the previous chapter. 这种高频交流电(AC)流产生前一章提到过的高频无线电波。
