4、er question ReadingSuppose that some material is connected to the terminals of an ideal voltage source u(t) as shown in Fig 6.2.Suppose that u(t)=1V， then the electric potential at the top of the material is 1V above the potential at the bottom. Since an electron has a negative charge, electrons in

5、the material will tend to flow from bottom to top. Therefore, we say that a current tends to go from top to bottom through the material. Listening and Answer question ReadingWe now present the first of Kirchhoff's two laws, his current law (KCL), which is essentially the law of conservation of e

6、lectric charge:Listening and Answer question ReadingWe now present the second of Kirchhoff's laws- the voltage law. To do this, we must introduce the concept of a "loop". Starting at any node in a circuit, we form a loop by traversing through elements and returning to the starting node

7、, and never encountering any other node more than once (Fig 6.4). Listening and Answer question ReadingStep and impulse functions are useful in determining the responses of circuits when they are first turned on or when sudden or irregular changes occur in the input. This is called transient analysi

8、s. However, to see how a circuit responds to a regular or repetitive input-the steady-state analysis - function that is by far the most useful is the sinusoid. 5315151312125課后作業(yè)布置：Translation: For a given circuit, a connection of two or more elements shall be called a node (Fig 6.3). At any node of a circuit, at every instant o
