江苏春晨电缆有限公司生产供应JXN电机引接线JXN电机引出线JXN电机电缆,电容器原理和计算公式及电容单位换算
The principle and calculation formula of capacitor and the conversion of capacitance unit

电容器原理
Principle of capacitor
在生产及生活实践中,科学家们发现,凡是被绝缘隔开的两个导体之间加以电压时,则接在高电位的导体就能容纳正电荷,接在低电位的导体能容纳负电荷。由此可见,上述导体和绝缘所构成的整体有容纳电荷的能力,这种能力叫做电容。而这个整体就叫做电容器。供应JXN电机引接线JXN电机引出线JXN电机电缆
In production and life practice, scientists have found that when the voltage between two conductors separated by insulation is high, the conductor connected to a high potential can hold positive charges, and the conductor at low potential can hold negative charges. Thus it can be seen that the above conductors and insulation have the ability to hold charge, which is called capacitance. And the whole is called the capacitor.
电容计算公式
Calculation formula of capacitance
实践证明:任一电容器容纳电荷的情况和一个篮球容纳气体的情况类似。篮球大气的气压越大,则容纳的气体越多;电容器所加电压越大,则容纳的电荷也越多。这样一来,要衡量它容纳电荷的本领,就必须在同一电压下来衡量,单位电压下所能容纳电荷的多少叫电容,用C表示,单位法拉:
It has been proved that the situation in which any capacitor holds the charge is similar to the situation in which a basketball holds a gas. The greater the air pressure in the atmosphere of the basketball, the more gas it holds; the greater the voltage the capacitor adds, the more charge it will hold. To measure its capacity to charge, it must be measured at the same voltage. The number of charges that can be charged under the unit voltage is called capacitance. It is expressed in C. The unit Fala:
电容计算公式
Calculation formula of capacitance
上公式中q是电容器在外家电压U时所容纳的电荷量。
In the formula q is the amount of charge on the capacitor voltage of the U contained in the home.
实际使用中常见的电容器的容量在其被制造出来时都有表明,电容器元件表面的数字或者色环就包含了容量信息。1法拉等于1库仑每伏特,即电容为1法拉的电容器,在正常操作范围内,每增加1伏特的电势差可以多储存1库仑的电荷。
The capacity of common capacitors in actual use is indicated when they are manufactured. The number or color ring of capacitor elements contains capacity information. Fala 1 is equal to 1 per Coulomb volts, namely capacitance of the capacitor 1 Fala, in the normal operating range, each additional potential 1 volts can store 1 Coulomb charge.
电容单位换算供应JXN电机引接线JXN电机引出线JXN电机电缆
Capacitance unit conversion
电容的容量单位是法拉(用字母F表示),但是在实际应用上,法拉这一单位太大了。往往使用最多的是微法(uF)或皮法(PF)。
The capacity unit is Fala (represented by the letter F), but in practical applications, Fala is too large. The most often used are micromethod (uF) or skin method (PF).
1F=1000,000微法=106微法(uF)
1F=1000000 micromethod =106 micromethod (uF)
1uF=1000,000皮法=106皮法(PF)
1uF=1000000 skin method =106 skin method (PF)
电容的大小与电容器的几何尺寸和介质的性质有关。除了电容器有电容外,在实际中,电气设备、线路与部件都具有自然形成的电容。如较长的输电线之间,较长的电缆都具有电容。
The size of the capacitor is related to the geometrical size of the capacitor and the properties of the medium. In addition to capacitors, in fact, in practice, electrical equipment, lines and components have natural capacity. Longer cables, such as long lines, have capacitances.
