Two bulbs B1 and B2 are connected in series with an source of emf 250V as shown in the figure 15 below. The labels on the bulbs read 250V, 80W and 250V, 100W respectively.
(i)[1.0]
What will be the ratio of the resistance of the bulbs R1/R2?
(a)5 : 4
(b)4 : 5
(c)1 : 1
(d)5 : 3
(ii)[1.0]
What will be the ratio of the power consumed (P1/P2) when connected in series?
(a)5 : 4
(b)4 : 5
(c)1 : 1
(d)5 : 3
(iii)[1.0]
