an alternating current applied to the stator’s windings creates a rotating magnetic field, while simultaneously inducing a current in the separate conductors attached to the rotor.
交流电通过定子线圈创造旋转磁场,导致镶在转子上的独立导体同时产生感应电流。
their job is to convert high-voltage alternating current from the mains into low-voltage direct current for mobile phones, laptops, ipods and other electronic gadgets.
其职能是将干线中的高压交流电转化为用于手机、笔记本电脑、ipod以及其他电子器械的低压直流电。
alternating current is different from direct current in that it constantly changes its direct of flow.
交流电与直流电的不同之处在于交流电不断地改变其电流流动方向。
a cycle is one complete reversal of an alternating current or voltage from zero to a positive maximum to zero again and then from zero to a negative maximum to zero again.
周期,是指交流电流或电压从零到正最大值再到零,然后从零到负最大值再到零这样一个往复的过程;
cycle a cycle is one complete reversal of an alternating current or voltage from zero to a positive maximum to zero again and then from zero to a negative maximum to zero again.
周期周期是指交流电流或电压从零到正最大值再到零,然后从零到负最大值再到零这样一个往复的过程;
for reasons the alternating current is more widely used than the direct current.
由于种种原因,交流电比直流电用得更为广泛。
mains electricity in america is supplied as alternating current at 60 hertz.
在美国,主要供应频率为60赫兹的交流电。
modern induction motors usually have three (or more) sets of stator windings, each using a different phase of the alternating current being applied.
现代的诱导式发动机一般都有三套固定子先去,每套使用施加的交流电不同的「相」。
an alternating current applied to the stator’s windings creates a rotating magnetic field, while simultaneously inducing a current in the separate conductors surrounding the rotor.
交流电用于定子的线圈而产生旋转磁场,同时在转子周围的单独导体内形成电流。
the main problem is that the alternating current created is very high frequency.

or electricity. in the early 1900s, after the standardization to alternating current distribution, hundreds of small electric utilities were consolidated into huge holding companies.
再举一个电力方面的例子,早在1900年,交流电标準发布以来,成千上万的小型电力公司合并成了大型的控股公司。
at the moment, data centres perform many conversions between alternating current (ac) and direct current (dc).
时下,数据中心要在直流电和交流电之间频繁转换。
the system generates a direct current, so using it to power dc devices locally is more efficient than switching to the alternating current needed to feed it back to the grid.
该系统产生的电流为直流电,所以用来驱动本地的直流点装置比将其转化为交流电输入电网来的更有效率。
alternating current is the current whose direction changes periodically.
交流电是其方向周期地变化的电流。
this vibration creates an alternating current that can be tapped.
电子振动又产生了可以利用的交变电流。
on top of that, the field generated by an alternating current interacts with the ground more strongly than it does with the air.
