1.	Two bulbs of 220 V and 100 W are first connected in series and then in parallel with a supply of 220 V. Total power in both the cases will be ______ .(A) 50 W, 100 W (B) 100 W, 50 W(C) 200 W, 150 W (D) 50 W, 200 W
Answer» n Series = P1 + P2 => 100 + 100=> 200 WPower in Parallel = 1/p1 + 1/p2=> 1/P = 1/100 + /100=> 1/P = 2/100=> 1/P = 1/50=> P = 50WTherefore, D is correct
