甲、乙同学分别做“测定小灯泡的电功率”实验，他们使用的器材中，电源电压相同且不变（为1.5伏的整数倍），滑动变阻器两个（分别标有“10Ω  2A”和“20Ω  2A”字样），待测的两小灯额定电压分别为2.2伏和6.3伏．甲、乙两同学各自选取一个变阻器、小灯及其它器材按要求正确连接电路，并进行实验．甲同学闭合电键后，发现移动滑动变阻器的滑片时电压表、电流表示数均有变化，但是小灯发光始终较暗；乙同学闭合电建后，观察到电流表示数为0.14安，当滑片移动到中点时（即滑动变阻器接入一半的电阻），小灯正常发光．

实验中所用的电源电压为____伏．乙同学所测小灯的额定电功率为____瓦，选用的滑动变阻器最大阻值为____欧．
