∵P=UI,∴灯泡额定电流:I
1=
=
=0.6A,I
2=
=
=0.5A,
∵I=
,∴灯泡电阻:R
1=
=
=10Ω,R
2=
=
=24Ω;
图甲两灯泡串联,要使其中一个灯泡正常发光而另一毕世裤个灯泡不烧坏,电路电流I=I
2=0.5A,
∵I=
,∴电压表示数U=I(R
1+R
2)=0.5A×(10Ω+24Ω)=17V,手简故A错误,B正确;
图乙中两灯泡并联,要使一返磨个灯泡正常发光而另一个灯泡不烧坏,电压表示数U=U
1=6V,I
1实=I
1=0.6A,
I
2实=
=
=0.25A,电流表最大示数I=I
1实+I
2实=0.6A+0.25A=0.85A,故C错误,D正确;
故选BD.
