Introduction
使用电容器并联和串联,可以创建电容器具有不同的属性和功能。当电流通过电容器,它创建了一个相反的电荷在每个盘子。您可能猜到,每个电极吸引相反电荷的大小相等,方向相反。
它们是什么,它们是如何工作的,以及为什么要使用它们?本教程将覆盖所有你需要知道的关于电容器的基本平行,以及提供一些建议如何使用它们在你的下一个项目。
Capacitors in Parallel
并联电路连接,两个点之间的所有电线导致每个组件,组件与导线。这意味着电容器年代第一和第二板块,分别连接到下一个电容器年代第一和第二板块。
连接并联电容器有助于增加电容的力量。这允许电能从电源或电池自由流动通过每个组件之前转储到最后一点。我们可以认为并联电容器是堆叠在彼此之上,所有的盘子中共享一个共同的电极。
例如, 如果我们有两个等值1美元mathrm{μF}电容器美元,然后我们可以认为他们是在功能上相当于一个2美元mathrm{μF} $电容器。
Working of Capacitors in Parallel
当两个或多个电容并联连接在一起,这意味着我们想增加电路的存储容量。个人的电容值保持不变,而他们的等效电容值是使用公式计算涉及所有的值。
让年代想象两个电容C <子> 1 < /订阅>和2 C <子> < /订阅>连接并联电路、电荷分为Q <子> 1 Q < /子>和<子> 2 < /订阅>,分别从C <子> 1 < /订阅>和2 C <子> < /订阅>

所以,a和b之间的总电荷
$mathrm{Q := :Q_1:+ :Q_2}$
$mathrm{Q = C_1V :+ :C_2 V}$
$mathrm{Q/V = C_1 :+ : C_2}$
$mathrm{C = C_1 :+ :C_2}$
在那里,
Q = Total Charge in circuit
V = voltage appped on the circuit
C = Capacitance power of capacitor
当我们添加大量的并联电容器
$mathrm{C_T = C_1:+ : C_2 :+ : C_3 :+ : C_4………. :+ : C_n}$
Example
假设有三个电容器;每一个都有50 nF的电容。然后连接与200年的供应。计算等效电容
解决方案:
$mathrm{C_1 := :C_2 := : C_3 := : 50: imes: 10^{-9} F}$
总电容并联
$mathrm{C_T = C_1 :+ : C_2 :+ : C_3 :+ :C_4………. :+ :C_n}$
$mathrm{C_T = (50+50+50) : imes:10^{-9}}$
$mathrm{C_T = 150:nF}$
Advantages of using Capacitors in Parallel
电容器是一个被动的电子组件,可以储存能量和交付需求。当我们连接并联电容器,它增加了电路的存储容量。
当连接交流电时,电容器抗拒改变电压和有几个电气性能,使其有用的作为电子电路的一部分。
这些包括的能力阻止直流(直流),同时允许交流(交流电)信号通过。的第一件事就是,当电容器并联连接,电压按比例减少。
连接并联电容器有助于减少电阻系统中使用。
Disadvantages of using Capacitors in Parallel
例如,两个0.1美元的并行组合mathrm{μF}电容器的等效电容0.2美元mathrm{μF} $,因为两个电容器将共享一个电压降(电压)的1 V总电容的每增加一倍。如果一个电容器是不小心允许流量通过另一个,可能有超过4一个瞬变电流通过电容器快速充电和放电。这种类型的电流可能导致严重损坏或两个单位,应该不惜一切代价避免不并联此类组件没有仔细考虑。
我们知道并联电容器储存巨大的能量,但他们释放这种能量在很短的时间。所以,这可以造成严重伤害或损坏电线。因为这个原因,它不是行业中使用的材料。
FAQs
Q1。并行计算在电容器。
答。我们需要做的第一件事是计算总电荷存储每个电容器,美元mathrm{问:T =σ文明:我}$,其中C我是每个电容器的电容和V是每个电容器的电压。
Q2。平行的电容器组合的规则是什么?
答。是当两个或多个电容并联的等效电容和个别电容器。他们相当于每个组件的组成部分。同样的适用于电阻和电感。
第三季。你为什么添加并联电容器?
答。添加并联电容器是一种常见的策略稳定放大器的增益。如果您添加两个电容器与不同的值,你可以增加稳定性以及低输入阻抗(假设都是相等的值)。正如我们将看到的,然而,有取舍当添加电容电路。
第四季度。什么因素影响电容并联电路?
Ans。理解电容和电容,你需要知道一个理想电容没有电阻,电压或电流:这些变量不相关的一个理想的电容器。如果电容器不理想,然而,它总是最佳实践设计一个电路的低电阻和电压的电容器。这意味着它将会有更少的耗散功率(低损失),将能够充电更快。
Q5。是电荷常数在并联电容器吗?
答,在并联电路中,电流分手并交付给所有组件。事实证明,有不止一个的思维方式如何电荷和电压在电容器并联工作。
Q6。如果平行板电容器上的电荷是一倍?
答。不改变电容电荷在两平行板电容器。电容器的电容变化只在配置。
