6A= ___ mA=___uA.60呢?0.6呢?20uA=____A=____m A.0.2呢?2呢?
6A= ___ mA=___uA.60呢?0.6呢?20uA=____A=____m A.0.2呢?2呢?
6A= ___ mA=___uA.60呢?0.6呢?20uA=____A=____m A.0.2呢?2呢?
6A=6000MA=6000000UA 60A=60000MA=60000000UA 0.6A =600MA=600000U A 20UA=0.00002A=0.02A 2UA=0.000002A=0.002MA 0.2UA=0.0000002A =0.0002MA
6A= ___ mA=___uA.60呢?0.6呢?20uA=____A=____m A.0.2呢?2呢?
20mA=___uA?20mA=___uA
ma=mb 为什么b不一定等于a呢?
300MA=?A
300mA=?A
0.6A=___mA=___μA 300mA=___A=____μA 60μA=____mA=_____A
2.5A= mA,300A= mA
1mA=10^?A ..
一A mA=?uA
0.2A=?mA?uA
1A=()mA.1mA=()ua
3A=多少mA?3mA等于多少uA?
分解因式:ma的平方-4ma+4a=
电流单位换算1.0.65A=___mA=___微安2.480微安=___mA=___A3.480mA=___微安=___A
1+A=-A-1ma
0.6A= mA uA=?A 450mA=?A=uA 0.25A=?mA
关于1A=?mA=?uA;1uA=?mA=?A;200ma=?A 的换算
F=ma和F=mg有什么区别?F-f=ma呢
