电路设计中零欧姆电阻的简介与功能

Introduction and Function of Zero Ohm Resistance in Circuit Design

电路设计中经常使用的一种元件是电阻。众人周知,电阻在电路中起着分压限流的作用。然而,在很多电路中,有时会遇到电阻值为零的电阻。既然欧姆电阻为零,它和导线有什么区别?为什么不把它们连起来呢?事实上,零欧姆电阻和直接导线连接是有区别的,并且零欧姆电阻在电路设计中有许多巧妙的用途。

A component often used in circuit design is a resistor.As we all know,resistors play the role of voltage divider and current limiting in the circuit.However,in many circuits,a resistance with zero resistance is sometimes encountered.Since the ohmic resistance is zero,what is the difference between it and the wire?Why not connect them?In fact,there is a difference between a zero-ohm resistance and a direct wire connection,and zero-ohm resistance has many clever uses in circuit design.
