    电位器

    电位器是什么？

    电位器是具有三个引出端、阻值可按某种变化规律调节的电阻元件。电位器通常由电阻体和可移动的电刷组成，当电刷沿电阻体移动时，在输出端即获得与位移量成一定关系的电阻值或电压。

    电位器的分类

    • 旋转电位器：可通过旋转主轴或旋钮来轻松控制。旋转电位器可以是单圈或多圈。
    • 滑动电位器：通常用于混音器，便于立即看出音量的位置与做淡入淡出控制。
    • 碳膜电位器：是在马蹄形的纸胶板上涂上一层碳膜制成。
    • 精密电位器：能以较高精度调节自身电阻值。

    电位器的作用

    • 用作分压器
    • 用作变阻器
    • 用作电流控制器
