margin-bottom: 0px; padding: 0px; line-height: 21px; color: rgb(85, 85, 85); white-space: normal; font-family: Tahoma; background-color: rgb(255, 255, 255);"><span style="word-wrap: break-word; margin: 0px; line-height: 24px; font-size: 16px; font-family: 黑體, SimHei;">①限流接法：將變阻器的一個固定端和滑動端接入電路，由于電阻可變，從而使電路中的電流發(fā)生變化。</span></p><p style="word-wrap: break-word; margin-top: 0px; margin-bottom: 0px; padding: 0px; line-height: 21px; color: rgb(85, 85, 85); white-space: normal; font-family: Tahoma; background-color: rgb(255, 255, 255);"><span style="word-wrap: break-word; margin: 0px; line-height: 24px; font-size: 16px; font-family: 黑體, SimHei;">②分壓接法：將變阻器的兩個固定端分別與電源的兩極相連，由滑動端和任一固定端連接到電路。由于電流通過變阻器的全部電阻絲，故A、B之間任意兩點都有電勢差。當滑動頭移動時，就改變了電路的輸入電壓。</span></p><p style="word-wrap: break-word; margin-top: 0px; margin-bottom: 0px; padding: 0px; line-height: 21px; color: rgb(85, 85, 85); white-space: normal; font-family: Tahoma; background-color: rgb(255, 255, 255);"><span style="font-size:
