    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">1、什么是电感</strong></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">电感(Inductance)是描述电路元件对电流变化产生的阻碍<span style="color: black;">功效</span>的<span style="color: black;">理学</span>量,其单位为亨利(Henry,简<span style="color: black;">叫作</span>H)。电感实质上是一种储存磁场能量的元件,当电流<span style="color: black;">经过</span>电感线圈时,线圈<span style="color: black;">周边</span>会产生磁场,磁场的<span style="color: black;">体积</span>与电流的<span style="color: black;">体积</span>成正比。当电流<span style="color: black;">出现</span>变化时,磁场<span style="color: black;">亦</span>会<span style="color: black;">出现</span>变化,<span style="color: black;">从而</span>在线圈中产生感应电动势,阻碍电流的变化。</p>
