[2]It may be that the inductor voltage rather than the current is the variable of interest in the ,人们感兴趣的变量是电感电压而不是电感电流。
B 三相电路
[1] Viewed in this light, it will be found that the analysis of three-phase circuits is little more difficult than that of single-phase circuits. 这样看来,三相电路的分析比单相电路的分析难不了多少。
[2] At unity power factor,the power in a single-phase circuit is zero twice each ,单相电路里的功率值每个周波有两次为零。
[3] It should be noted that if the polarity of point A with respect to N ( ) is assumed for the positive half-cycle, then when used in the same phasor diagram should be drawn opposite to, or 180° out of phase with, .应该注意,如果把A点相对于N的极性( )定为正半周,那么在用于同一相量图中时就应该画得同相反,即相位差为180°。
A 运算放大器
[1] One problem with electronic devices corresponding to the generalized amplifiers is that the gains, AU or AI, depend upon internal properties of the two-port ,一个问题就是增益 AU 或者AI ,它们取决于两输入端系统的内部特性。
[2] This is one of the key features of Op-Amp design—the action of the circuit on signals depends only upon the external elements which can be easily varied by the designer and whic
