我们知道,最基本的电路有串联电路和并联电路.串联电路的元件逐个顺次连接,元件之间相互影响,如开关、滑动变阻器与被控制的元件串联,电流表与被测部分串联;并联电路的元件并列连接在电路两点间,各部分互不影响,如电压表与被测部分并联.如何连接简单电路?下面介绍两种方法: We know that the most basic circuit is a series circuit and a parallel circuit. The components of a series circuit are connected one after the other, and the components interact with each other. For example, a switch, a sliding rheostat and a controlled element are connected in series, an ammeter is connected in series with a measured part, and a parallel circuit is connected. The components are connected in parallel between the two points of the circuit. Each part does not affect each other. For example, the voltmeter is connected in parallel with the measured part. How to connect a simple circuit? Here are two methods:
