在学习电路分的过程中,常常因为路中连有滑动变阻电压表、电流表等器件,或因路过于复杂而影响我们的判力,从而导致错误的分析和论。现总结几个较易掌握的法,帮你扫除障碍.一、“切断法”突破滑动变阻器的障碍二、突破电压表的障碍图1图2在电路图中,常通过移动变阻器上的滑片来? In the course of learning circuit points, often because of the sliding varistor voltage meter, ammeter and other devices in the road, or because the road is too complicated and affect our judgment, leading to erroneous analysis and theory. Now summarize some of the more easy to grasp the law, to help you remove obstacles. First, the “cut-off method” to break through the obstacles of the sliding rheostat Second, the barrier to break the voltmeter Figure 1 Figure 2 In the circuit diagram, often by moving the varistor slider ?
