(10分)某同学在用电流表和电压表测电池的电动势和内阻的实验中,串联了一只2.5 Ω的保护电阻R0,实验电路如图所示.

(1)连好电路后,当该同学闭合电键时,发现电流表示数为0,电压表示数不为0.检查各接线柱均未接错,接触良好且未发生短路;他用多用电表的电压挡检查电路,把两表笔分别接a、b,b、c,d、e时,示数均为0,把两表笔接c、d时,示数与电压表示数相同,由此可推断故障是_______________.

(2)按电路原理图,用多用电表的电压挡检查电路,试把两表笔分别接c、d时的实物电路图以画线代替导线连接起来.

(3)排除故障后,该同学顺利完成实验,测量得到下列数据,电池的电动势为________,内阻为________.

I/A0.100.170.230.30
U/V1.201.000.800.60
(4)考虑电表本身电阻对测量结果的影响,造成本实验的系统误差的原因是_________.

What’s in a surname You may ask. A new website project has been released, that helps you (1) . Have you ever wondered why your ancestors gathered where they did, or where others with your surname live now A research project (2) in Britain answers these questions. And another study has found the surnames are (3) .
"Smith", for example, remains the most common surname in Britain. Used by (4) people, it has exactly the same concentration it always did in Lerwick, in the Scottish Shetland Islands. "Jones" is (5) , and is the most common among hill farmers (6) .
The data used for this project comes partly (7) . A number of other files are held by Expairing, which is probably Britain’s (8) .
There’ re some of us who are fairly predictable. "Campbell", for example, as you might expect, is somewhat concentrated (9) , and it appears really bizarre to be found anywhere else.
Well, with 25,000 names as (10) , what you can do is put them in general categories, if, for example, you look at (11) . Like the name Webber, you might find it is much more common in the Midlands than (12) . If you go to Wales, most people get their names (13) . And in Yorkshire for example, a lot of people have names (14) that they originally lived in or at least their ancestors did.
Well, we only have 25, 000 names on this website, but there’re (15) now found in Britain and they’ re particularly interesting, for (16) . Most British names are fairly common. And about what we can now do as such is look for (17) from different parts of the world and different faiths, (18) . And what there is in names is actually extremely useful, for researchers in (19) may find a lot about (20) now living in this country.
