 如图所示是检测某一传感器的电路图，这种传感器上标有“6V、1.8W”的字样（该传感器可看作一个纯电阻电器），滑动变阻器上标有“10Ω、1A”的字样，电流表的量程为0～0.6A，电压表的量程为0～3V．求：

   My name is Chen Lan. My home is in Gulangyu. Do you know it? It is in Xiamen. It is near the sea(海). Gulangyu is a small place，but it is very nice and clean. There are no cars，no buses. People only walk. So it is very quiet.
