当它附着在大鼠心脏时，纳米发电机产生了每3毫伏上下大约30微微安培的电流。
When it was attached to the rat's heart, the nano-generator produced about 30 pico-amps at about three millivolts.
当连接到大鼠的横隔膜时，该动物的呼吸使纳米线得到伸展，并产生少量的电力——每两毫伏约4微微安培电流。
When attached to the rat's diaphragm, the animal's breathing stretched the nanowire, and it generated a tiny amount of electricity — about four pico-amps of current at two millivolts.
当一个未知的信号被连接到测量装置时，例如伏特计或安培表，测量准确度则几乎完全由测量装置决定。
When an unknown signal is connected to a measuring device, such as a voltmeter or ammeter, the measurement accuracy is almost entirely determined by the measuring device.
然而，实际的安培计在输入端开路时的确有一些小的电流。
Practical ammeters, however, do have some small current that flows when the input is open.
使用分流型安培计(图2 -49)时，输入电容对电流测量的影响与电压测量时类似。
The effects of input capacitance on current measurements using a shunt type ammeter (Figure 2-49) are similar to those for voltage measurements.
这就是所谓的20小时评价与其他评级的基础上的时代，如5日，8日和100个小时，而且在不同的安培利率。
This is known as the 20-hour rating versus other ratings based on times such as 5, 8 and 100 hours, but also at different amperage rates.
磁通势单位等于安培的电流通过单位线圈时产生的磁通势；等于（待查表）吉伯。
A unit of magnetomotive force in the meter-kilogram-second system equal to the magnetomotive force around a path linking one turn of a conducting loop carrying a current of one ampere.
订购保险丝时，请注明额定电流安培数和电压。如果需要确定适当的尺寸，请参阅美国国家电气规程。
When ordering fuses, specify Ampere rating and voltage. Refer to the National Electrical Code for proper sizing.
