However, if the resistor is too large, it may affect measurement accuracy.
然而,如果电阻器太大,它可能会影响测量准确度。
It is, of course, important to choose the resistor so that it neither degrades the noise performance of the system nor allows too much current to pass under fault conditions.
因此,限流电阻的选择十分重要,既要限制故障电流,又不能引入太大的噪声。
The varistor and the resistor are mounted externally.
变阻器和电阻器安装在外面。
