如圖所示電路中,L是一電阻可忽略不計(jì)的電感線圈,a、b為L(zhǎng)上的左右兩端點(diǎn),A、B、C為完全相同的三個(gè)燈泡,原來(lái)電鍵K是閉合的,三個(gè)燈泡均在發(fā)光。某時(shí)刻將電鍵K打開(kāi),則下列說(shuō)法正確的是()
A.a點(diǎn)電勢(shì)高于b點(diǎn),A燈閃亮后緩慢熄滅
B.b點(diǎn)電勢(shì)高于a點(diǎn),B、C燈閃亮后緩慢熄滅
C.a點(diǎn)電勢(shì)高于b點(diǎn),B、C燈閃亮后緩慢熄滅
D.b點(diǎn)電勢(shì)高于a點(diǎn),B、C燈不會(huì)閃亮只是緩慢熄滅
