装修房子期间,小明准备为酒柜安装小射灯(额定电压为12V),他把小射灯直接接入家庭电路后,刚一通电小射灯的灯丝就被烧断了,经检查发现,还有一个配件忘记安装了。

(1)没有安装配件导致小射灯被烧坏的原因是小射灯的实际电压__________额定电压。

(2)小明想知道灯丝电阻随温度变化的规律,他利用实验室的器材设计了图甲所示的电路,小灯泡的额定电压为2.5V。闭合开关后,发现小灯泡不发光,经检查是由于某根导线断了造成的。他又利用图乙的电路对图甲的电路进行检测。检测时他应该将图甲中的开关__________,若检验灯发光说明被检测导线_________(选填“断了”或“没断”)。

(3)更换导线后,正确进行实验并将数据填人下表(电源电压恒为4V)。分析实验数据发现:温度越高,灯丝电阻越_________。根据表中的数据分析,下列滑动变阻器的规格符合实验要求的是_______。

A.30Ω 0.2A

B.20Ω 1A

C.10Ω 1A

D.5Ω l.5A

(4)小明查找资料,发现大多数金属的电阻都具有和灯丝电阻随温度变化规律相同的性质。他用一段具有这种性质的金属丝代替小灯泡接入图甲的电路中,并将滑动变阻器的滑片调到适当位置固定不动,设计了一个简易的测温装置。若要满足温度升高时测温装置的示数变大,应将图甲中_________表的表盘改装成测温装置的刻度盘。
