However , in the case of short - circuiting, its impedance immediately increases to limIt'short - circuit current .───发生短路故障时, 超导限流器的阻抗迅速增大以限制 短路电流.
Current reflection of high impedance is negative.───低阻抗之电压反射为负.
An impedance discontinuity causing an undesired signal reflection in a transmission cable.───阻抗的不连续将导致传输电缆中不希望发生的信号反射.
These figures show that the improvement of input impedance is within a factor of ten.───这些数字表明,输入阻抗的改进值为一个数量级.
This resulting increase in impedance between the electrodes may be observed on a pen recorder.
Its high input impedance means that it does not load a signal source which it copies at its output.
Negative series-inserted feedback always raises the input impedance while negative shunt-inserted feedback reduces it.
