长期以来,有一个幽灵,一直盘旋在广大电子爱好者的脑海中,那就是基尔霍夫定律。我们在看一些电子电路相关文章的时候,经常会看到作者提到“根据基尔霍夫定律”,然后吧啦吧啦一大堆,每到此时,我的的表情总是这样的: 今天,我们来一起学习一下基尔霍夫定律(Kirchhoff Circuit Laws)。 一般来说,年代越久远的知识越好学,刚刚新鲜出炉

KVL, and Ohm’s law.” With these three concepts, just about any electrical circuit can be analyzed and understood. Granted, things get a little more complicated when you add concepts like inductance and capacitance, but KCL, KVL, and Ohm’s law form the ...
“图”的概念:对于任何一个由集总参数元件组成的电路,可以不问元件的性质,只考虑元件之间的联接关系,而将电路中的每个元件用一条线段代替,仍称之为支路,此线段可以是直线也可以是曲线;将每个元件的端点或若干个元件相连接的点(即节点)用一个圆点表示,仍称之为节点。将电路元件抽去,把每一条支路画成抽象的线段...
1、电路:是由若干电路部件(电阻器、蓄电池等)和电路器件(晶体管、集成电路等)连接而成具有特定功能的电流闭合通路装置(实际电路),也成为电网络。 【电路(circuit);网络(network);系统(system)。】 2、手电筒电路 电池:电源;灯泡:负载; 3、扩音机电路 ...

电路 基尔霍夫定律 KVL and KCL Kirchhoff's Laws and Circuit Analysis (EC 2) •Circuit analysis: solving for I and V at each element •Linear circuits: involve resistors, capacitors, inductors •Initial analysis uses only resistors •Power sources, constant voltage and current •Solved ...
Consider KVL for the circuit shown. Let VS=5.7VandR=1000Ω The box is unknown(it could be an open, a short, or some element). (a)Calculate the voltage V when the current I=0. (b)Calculate the current I when the vo...
Both KVL and KCL are prominent inevery single trace that you created on a PCB. Sometimes, it’s obvious that one of the rules apply while others don’t have KVL and KCL screaming from the circuit. However, it’s evident that forgetting these rules aren’t the best things to do in PCB...
