小明探究“通过导体的电流与电压的关系”时，电路图如图 (甲) 所示．电源电压不变，为定值电阻，电流表A 选用0～0.6 A量程，电压表选用为0～3 V量程，电压表选用为0～15 V量程，滑动变阻器上标有“50 Ω 1A”的字样．

（1）请根据电路图(甲) 用笔画线代替导线连接实物图(乙)中电压表V₂的连接．   ____ 
（2）如图 (甲)中闭合开关前滑动变阻器的滑片P应放在____ （选填“A”或“B”）端．
（3）闭合开关S，发现电流表A 与电压表的示数为零，电压表的示数不为零，则电路存在的故障是____ ．
（4）排除故障后，继续进行实验，记录电流表A与电压表的示数，得到一组实验数据，如表格(丙) 所示．分析表中实验数据可得结论：____ ．

（5）实验中，记录电流表A 与电压表的示数，得到一组实验数据，根据实验数据作出图线，如图(丁)所示，电源电压是____ V．在保证实验器材安全的前提下，滑动变阻器接入电路的阻值不得小于____ Ω．

    He is quiet and shy．He likes to hide his eyes behind his hair. He doesn't smile very often. However， if you talk to him about music， he will have a lot to say.

    This is Jay Chou， a pop singer in Taiwan. He was born（出生）on January 18th. He's 36 years old now. His fans were so excited because he sang songs in Beijing on September 12 in 2003．And the album Ye Huimei was released（发行）in July and was named after（以……取名）his mother.

    Jay grew up just with his mother. He did not talk much and did badly in many school subjects.

    His mother noticed the boy's special interest in music and sent him to learn the piano when he was only three years old．He loved it and kept on practicing.

    Jay is not very handsome， but he has big crowds of fans.
