1·Because the source of the energy stops, the electrical current stops -just as a light bulb turns off when you switch off the electricity running to it.
因为一旦能量的来源被切断了，电流就会被切断——就好像当你关上开关，切断电流的时候，灯泡会立刻熄灭一样。
2·Because the source of the energy stops, the electrical current stops - just as a light bulb turns off when you switch off the electricity running to it.
因为一旦能量的来源被切断了，电流就会被切断——就好像当你关上开关，切断电流的时候，灯泡会立刻熄灭一样。
3·Typical smart meter designs include periodic transmission of current, phase, and frequency data from the user to the electricity distribution company.
典型的智能度量设计包括来用户端的电流、相位和频率数据向电力调配公司的周期传送。
4·It stands to lose over 70 percent of its current electricity supply when South Africa, recently beset by power shortages, halts energy exports to Botswana by 2013.
如果最近遭遇了电力短缺的南非在2013年停止向博茨瓦纳出口能源的话，它将失去目前电力供应的70%以上。
5·Worldwide, wind energy under the same constraints could supply at least 40 times the current electricity consumption.
在世界范围内，在相同条件下的风能能够提供是现在电力消耗40倍的能量。
6·At Sheep Dog, which is twice the size of our current home, to use solar panels to effectively heat the whole house, we'd probably have to cover an acre or two to get enough electricity.
牧羊犬洼地的面积，相当于两个我现在所住的房子，如果在那里使用太阳能电池板取暖的话，我们可能就要覆盖一到两英亩的面积去获取足够的电力了。
7·Wind turbines off US coastlines could potentially supply more than enough electricity to meet the country's current electricity demand, the US interior department reported today.
美国内务部今天报告称，在美国海岸线设置风力发电机可以长期提供超过国家目前电力需求的电能。
8·We're trying to set an example because the country may face a severe electricity shortage if the current pace (of heating consumption) continues.
我们尽量以身作则，如果人们还按照现在的速度来消耗热量，那么韩国可能会面临严重的电荒。
9·Though the current in each nantenna is small, an array of them can produce a useful amount of electricity.
虽然单个纳米天线中生成的电流很小，但大量纳米天线组成的阵列就足以产生可以使用的电量。
10·When no electricity is delivered, a voltage difference between the electrodes drives a current in the other direction.
当没有电流流通时，电极之间的电压差驱动电子反方向流动。
