The fundamental limit to measurement is Johnson noise in the source resistance.

对测量的基本限制是源电阻中的约翰逊噪声。

As shown in Figure 2-2, the input bias current (IBIAS) develops an error voltage across the source resistance (RS).

如图2 - 2所示，输入偏置电流(IBIAS)在源电阻(RS)上产生了误差电压。

For example, if the desired accuracy is 1%, then the meter resistance must be more than 100 times the source resistance.

例如，如果希望的准确度为1%，那么表的输入电阻必须比源的电阻高100倍。

It is the unique source of human assertiveness and aggressiveness as well as the source of resistance to the aggression of others.

这是人类魄力与进取的特殊泉源,但同时也是,抵制他人进犯的由来。

The source of that frustration used to be the Germans' seeming resistance to ever making a mistake.
