43.如图24所示的电路中,电源两端电压不变,设灯L电阻不变。当开关S1闭合,S2断开,滑动变阻器的滑片P移到B端时,R1的电功率为P1,电流表示数为I1;当开关S1断开,S2闭合时,R1的电功率为P1′,电流表示数为I2,此时灯L正常发光。当开关S1、S2都断开,滑动变阻器的滑片P在C点时,变阻器接入电路的电阻为Rc,电压表V1的示数为U1,电压表V2的示数为U1,已知U1:U2=3:2,Rc的电功率为18W,P1:P1′=9:25。电路通过断开、闭合开关以及滑动变阻器滑片P的移动,形成不同电路所消耗的最大电功率与最小电功率之比为3:1。求:

(1)电流I1与I2的比值;

(2)灯的电阻R1与R1的比值;

(3)灯L正常发光2min所消耗电能W的大小。(请画出相关电路状态的等效电路图)
