用两个相同的小量程电流表,分别改装成了两个量程不同的大量程电流表A_1、A_2,若把A_1、A_2分别采用串联或并联的方式接入电路,如图1所示,则闭合开关后,下列的说法正确的是A.图1中的A_1,A_2的示数相同B.图1中的A_1,A_2的指针偏角相同C.图2中的A_1,A_2的示数和偏角都不同D.图2中的A_1,A_2的指针偏角相同看罢了上面的题,你或许会会心的一笑,这是一道经典的 With two same small-scale ammeter, were modified into two different ranges of large-scale ammeter A_1, A_2, if A_1, A_2, respectively, in series or parallel connected to the circuit, as shown in Figure 1, the closed switch After the following statement is correct A. A 1 in Figure 1, A_2 show the same number B. Figure 1 A_1, A_2 pointer declination same C. Figure 2 A_1, A_2 of the number and declination Are different D. In Figure 2, A_1, A_2 pointer angle same look at the above questions, you may be a smile, this is a classic
