小明同学在做“测定小灯泡的额定功率”实验时,选取了一个标有“2.5V”的小灯泡和必要的器材,用导线把实验器材连接起来,如图所示.

(1)在开始测量前,请你帮助小明检查实验器材的连接图,如果错误,在图中错误的连线上打“×”,再用笔画线画出正确的连线(要求改动的连线最少).

(2)经检查改正连线后,小明连续进行了4次测量.并把测量得到的数据和观察到的现象填写在下面表格里.

次数电压/V电流/A灯泡亮度
11.500.32发光微弱
22.200.38较暗
32.500.40正常发光
43.000.45很亮
请你帮小明分析上表中的数据和现象,可得到:______;

①小灯泡的额定功率是______W;

②小灯泡逐渐变亮,表明灯丝温度逐渐______;

③小灯泡逐渐变亮,灯丝的电阻逐渐______;

④由此可知灯丝的电阻是随着温度升高而______.
