判断电路图中的电表是电流表还是电压表的问题,既能考查同学们对电表使用方法的掌握情况,又能考查同学们观察、判断和推理的能力.这类问题的情景具有模糊性,解答方法比较灵活,下面介绍几种方法,供同学们参考.一、直接观察法直接观察电路中的电表接入电路的方式.若电表与其他元 Judging whether the meter in the circuit diagram is an ammeter or voltmeter problem, it can not only examine the students’ grasp of the use of the meter, but also examine the ability of the students to observe, judge and reason. The situation of such problems is vague and the method of solution More flexible, the following describes several methods for students to refer to. First, the direct observation method to directly observe the way the meter access circuit in the circuit. If the meter and other elements
