电压

• The relation between terminal voltage and terminal current is called a terminal characteristic .
  输出端口电压和输出端口电流间的关系称为外特征。
• The time harmonics can be considered as voltages of higher frequencies applied to the windings .
  时间谐波可以看作是施加在绕组上的较高频率的电压。
• It is therefore advisable never to use an excessively high working voltage for a multiplier cell .
  因而光电倍增管不使用过高的工作电压是很有道理的。
• In the foregoing example, the voltage source is nonideal and hence presents no difficulty .
  在上面的例子中，电压源是非理想的，所以没有发现什么困难。
• A 0 bit or off switch is represented by the absence of any voltage on the conductor .
  当导线上电压消失时，就表示该位数字为“0”，即开关的“断”状态。
• It is difficult to produce a very high voltage directly, by a combination of transformer and rectifier .
  用变压器和整流器相配合直接得到很高的电压是困难的。
• And the excitation voltage and output were also fed through the selector switch to the digital voltmeter .
  其激励电压和输出也通过选择开关接到数字电压表上。
• we say that current leads the voltage by 90° or that the voltage lags the current by 90°.
  我们说电流超前电压90，或电压落后于电流90。
• Clip-gage excitation was supplied by a commercially available power supply (signal conditioner) .
  回形引伸计的激励电压由商售的通用电源装置（信号调制器）来提供。
• Only transformer coupling can contribute to the voltage gain of an amplifier by virtue of a stepup turns ratio .
  只有放大器耦合方能通过开压匝数比提高变压器电压增益。
