如图是某同学测定“小灯泡功率”的实验电路图小灯额定电压为2.5V．在实验中至少要多次调节滑动变阻器电键闭合前滑片P应处于选填“a”或“b”端其目的是使然后接通电路再次调节目的是使．在实验时测得的数据如表．在整理数据计算功率时发现其中一次实验结果与其他两次实验结果相差很大经检查原来是有一个电流的示数读错了．该同学选用的电流表的量程是0﹣0.6安．试分析数据表中第次电流的读数错了正确的应为小灯泡额定功率P额＝瓦．
某兴趣小组在进行测定小灯泡额定功率实验时可用的实验器材有标有“0.2安”字样的小灯泡3节新干电池标有“10欧1安”和“5欧1安”的滑动变阻器电压表电流表电键和导线若干所有器材均完好．他们第一次选择了3节新干电池和标有“5欧1安”的变阻器及其它相关器材进行实验实验电路连接正确步骤规范但在实验过程中发现无法完成实验．接着他们更换了部分器材使用2节新干电池和标有“10欧1安”的变阻器重新进行了第二次实验但在实验过程中发现依旧无法完成实验．然后他们经商量对器材又做了一定的调整最后顺利地完成了实验． 1请画出正确的实验电路图． 2请分析他们第一次实验时无法完成实验的原因是． 3该小灯泡的额定功率应介于瓦至瓦之间．
图a所示仪器的名称是用来测量物体的在电学实验中电流表应该在电路中选填“串联’’或“并联”图b中电流表的示数为安．
