要测量小灯泡的额定功率实验室提供的器材有标有2.5V的小灯泡电池组电压为3V电压表电流表滑动变阻器开关导线若干．1小虎所接的实验电路如图甲电路中部分连接不合理但只需改动一根导线即可使电路连接正确．请你在应改动的导线上打×并用笔画线代替导线画出正确的接法．2改正电路后移动滑片使滑动变阻器接入电路的阻值最大．闭合开关此时电压表示数为1V电流表示数为0.2A则滑动变阻器的最大阻值为Ω．3连接好实验电路检查连接无误后闭合开关S却发现灯泡不发光电流表无示数电压表指针偏转明显可能发生的故障是．A．灯泡灯丝断了B．灯座接线短路C．蓄电池没有电了D．电流表接线柱短路．4在发现电路有故障时首要的规范操作应是．5故障排除后移动滑动变阻器的滑片使电压表的示数为2.5V此时电流表示数如图乙所示其值为A小灯泡的额定功率为W．6她还注意到这个实验记录也可以用来计算灯丝的电阻请完成表格中内容．这位同学有些纳闷儿导体的电阻不是与电压电流无关吗怎么三次计算的灯丝电阻却不一样呢请你对此作出解释．

近年来有关家庭厨房火锅店加油站等地因人们操作不当引发爆炸的新闻多有报道． 1某女士在厨房中一边用煤气灶炒菜一边向肉中倒入大量生粉引发了爆炸导致烧伤．发生爆炸的原因是在密闭的空间内由于生粉属于填“可燃物”或“助燃物”在空气中扩散后遇到煤气灶的明火生粉迅速被而发生爆炸． 2某车主在加油站加油时闻到了刺鼻的汽油味这说明汽油分子在．车主在加油管口附近打电话而引起了爆炸据此建议加油站要在显眼处贴上的告示． 3某女士在火锅店就餐时服务员未将干锅炉内的固体酒精熄灭就直接加入几块固体酒精酒精剧烈燃烧引燃了该女士身体导致大面积烧伤这警示我们在实验室中不能向的酒精灯添加酒精．
