Two bulbs B1 and B2 are connected in series with AC
source of emf 200 V,
as shown. Thelabels on the bulbs read 200 V-60 W
and 200 V-100 W respectively. Calculate the ratio of: (i) the resistances of the bulbs (R1/R2), (ii) the power being consumed when connected in series (P1/P2), (iii) the PD across the bulbs (V1/V2).
