刻度盘上的刻度表示电流强度的安培数。

The scale is marked to show the strength of the current in amperes.

比如，质量单位千克，热力学温度开尔文，能量单位焦耳，电流强度单位安培，力单位牛顿等。

Such as kilogram of mass unit , Kelvin of thermodynamic temperature , Joule of energy unit , Ampere of electric current intensity and Newton of force unit and so on?

阻抗是对电的抵抗力——小孩子也略有所知，是电压和电流强度的比值。

Impedance is related to resistance-which, as generations of schoolchildren have had drummed into them, is the ratio of voltage to current.

在电鳗的身体中，五分之四的细胞都是专门用来发电的。电鳗能释放的电流强度大体上与它的身体长度相一致。

As many as four-fifths of all the cells in the electric eel's body are specialized for generating electricity, and the strength of the shock it can deliver corresponds roughly to length of its body.
