Answer» $\:\:\:\: \huge {\underline{\underline{\sf{Solution\::}}}}$ • Here two lamps are connected in series therefore power consumed by the lamps will BECOME parallel combination of two given POWERS : Now , P1 = 200 W and P2 = 200 W $\sf Power\: =\: \dfrac{(P1×P2)}{(P1+P2)} \\$ $\sf Power\: =\: \dfrac{(200×200)}{(200+200)} \\$ $\sf Power\: =\: \dfrac{(40000)}{(400)} \\$ $\:\:\:\: \large\underline{\boxed{\sf{Power\:=\:100\:W}}}$ • Option B is correct i.e. 100 W and 100 W _________________________
