(1)某同学欲将量程为200μA的电流表G改装成电压表。

①该同学首先采用如图所示的实验电路测量该电流表的内阻Rg,图中R1、R2为电阻箱。他按电路图连接好电路,将R1的阻值调到最大,闭合开关S1后,他应该正确操作的步骤是       。(选出下列必要的步骤,并将其序号排序)

a.记下R2的阻值

b.调节R1的阻值,使电流表的指针偏转到满刻度

c.闭合S2,调节R1和R2的阻值,使电流表的指针偏转到满刻度的一半

d.闭合S2,保持R1不变,调节R2的阻值,使电流表的指针偏转到满刻度的一半

②如果按正确操作步骤测得R2的阻值为500Ω,则Rg的阻值大小为    ;(填写字母代号)

A.250Ω

B.500Ω

C.750Ω

D.1000Ω③为把此电流表G改装成量程为2.0V的电压表,应选一个阻值为    Ω的电阻与此电流表串联。

     I am so exciting that I can’t wait to share with you what I experienced today. I gave my first lesson

in our school, which left me the deep impression.

  When I entered into the classroom, my students began to make much noise. I stood on the platform,

knowing what to do at first. But soon I realized everything must be done. I asked the kids that they liked

English songs. They all say “Yes.” I sang a song I had practiced many times. To my great surprise, all the

kids turned their attentions to my class.

     From this experience I know however happens, we must stay calmly at first and find a wise solution.
