UF是一个电容单位。uF表示微法。
1uF表示1微法,微法表示电容大小的单位,英文符号为μF中文称为微法。
1μF= 10^(-6)F,大多数电容的大小为0.1至0.01μF左右。
一个电容器,如果带1库的电量时两级间的电势差是1伏,这个电容器的电容就是1法拉,即:C=Q/U 。
但电容的大小不是由Q(带电量)或U(电压)决定的,即电容的决定式为:C=εS/4πkd 。其中,ε是一个常数,S为电容极板的正对面积,d为电容极板的距离,k则是静电力常量。
扩展资料:
在国际单位制里,电容的单位是法拉,简称法,符号是F,由于法拉这个单位太大,所以常用的电容单位有毫法(mF)、微法(μF)、纳法(nF)和皮法(pF)等。
电容之间的换算关系是:
1法拉(F)= 1000毫法(mF)=1000000微法(μF)。
1微法(μF)= 1000纳法(nF)= 1000000皮法(pF)。
UF is a unit of capacitance. uF stands for micromethod.
1uF indicates 1 micromethod, and micromethod indicates the unit of capacitance size. The English symbol is μF and the Chinese word is micromethod.
1μF= 10^(-6)F, and most capacitors are around 0.1 to 0.01μF in size.
A capacitor, if with 1 library of electricity when the potential difference between the two stages is 1 volt, the capacitance of this capacitor is 1 farad, that is: C=Q/U.
However, the size of the capacitor is not determined by Q (charge) or U (voltage), that is, the determination of the capacitor is: C=εS/4πkd. Where ε is a constant, S is the opposite area of the capacitor plate, d is the distance of the capacitor plate, and k is the electrostatic constant.
Extended information:
In the international System of units, the unit of capacitance is farad, referred to as the law, the symbol is F, because the farad unit is too large, so the commonly used capacitance units are millimetre (mF), micromethod (μF), nanomethod (nF) and skin method (pF).
The conversion relationship between capacitors is:
1 farad (F) =1000 milliways (mF) =1000000 microways (μF).
1 micromethod (μF) = 1000 nanomethod (nF) = 1000000 picomethod (pF).
