闭合电路中的路端电压是指电源两端的电压,也称电源的输出电压,又叫外电路上的电压。理清路端电压的含义对闭合电路的计算及相关的电路分析无疑有很大的帮助。本文从三个角度来剖析、理解闭合电路中路端电压的含义,并通过数形结合与等效方法来解决闭合电路中一些常见的物理问题。1.闭合电路中路端电压的三种理解(1)外电路上的电压通常我们把闭合电路分成内、外二部分,其基本结构如图1,主要物理量有:电动势E、内电阻
Road closed circuit voltage is the voltage across the power supply, also known as the power supply output voltage, also known as the voltage on the external circuit. To clarify the meaning of road voltage on the closed-circuit calculation and related circuit analysis is undoubtedly a great help. This article analyzes from three perspectives to understand the meaning of the terminal voltage in the closed circuit and to solve some common physical problems in the closed circuit through the combination of number and form and equivalent method. 1. Closing circuit three kinds of road terminal voltage understanding (1) the voltage on the external circuit Usually we close the circuit is divided into internal and external two parts, the basic structure shown in Figure 1, the main physical quantities are: electromotive force E, the internal resistance
