    欧姆表

    欧姆表是什么?

    欧姆表,又称电阻表,是直接测量电阻值的仪表。

    欧姆表的工作原理

    欧姆表是根据闭合电路的欧姆定律制成的,其工作原理是传递小电流通过样品,使仪器测量压降以及一个物体在允许电流流过时的电阻值,以欧姆为单位突出显示电阻。

    欧姆表的分类

    • 欧姆表有多种尺寸、电压和类型可供选择,每种都具有不同的精度。
    • 欧姆表(或电阻表)有三种主要型号,包括微欧姆表(用于测量低电阻)、通用标准欧姆表和兆欧表(用于测量高电阻),所有这些测量电阻的单位均为欧姆。
    • 不同类型的欧姆表具有不同的灵敏度级别,包括微欧、兆欧和毫欧。

    欧姆表的应用

    • 实验室和研究环境
    • 生产场所
    • 家庭故障排除
