Why to learn the circuit analysis?
為什么要學習電路分析？
Because it is one of the important theoretical basis of electrical, electronic and information science and technology. It can make us understand the characteristics of the circuit. To solve the engineering problems.
因為它是電力電子和信息科學技術的重要理論基礎之一，它可以幫助我們理解電路中的特性辆它，以便解決工程上的問題.
Ok I know, and what are the analytical methods of the circuit?
好的，我知道剧腻，那么電路中有什么分析方法呢？
In brief, there are equivalent method and equation method, equivalent method is simplified primary circuit, suitable for local variables. And equation method is according to the basic principle of the circuit, the equation is solved.
簡而言之，有等效法和方程法渴杆，等效法是把電路化簡寥枝，適合于局部電路，方程法是根據(jù)電路基本原理列方程解決.
You say that equation method is according to the basic principle of the circuit, the equation is solved, then what basic theorems are needed to be used in constructing equations, can you give an example?
你剛剛說方程法是根據(jù)電路基本原理列方程解決磁奖，那么在構造方程時需要用到什么原理呢囊拜？可以舉一個例子嗎？
Sure. For example in the lumped circuit, any moment, to any node, the algebraic sum of the branch current of all the outflow nodes is equal to zero, this is KCL.
當然可以比搭，例如在集總電路中冠跷，任何時刻，對任一結點身诺，所有流出結點的支路電流的代數(shù)和恒等于零蜜托，這是基爾霍夫電流定律.
Can you tell me about the difference between dynamic and static circuits?
你可以告訴我動態(tài)電路和靜態(tài)電路的區(qū)別嗎？
Ok, in short, if there is a variable resistor in the circuit, it is the dynamic circuit, otherwise it is a static circuit.
當然戚长，簡單來說盗冷，如果電路中存在可變電阻怠苔，它就是動態(tài)電路同廉，反之為靜態(tài)電路.
