HEY DEAR . ✌
______________________________
As the electrical bulbs have resistances in ratio 1:2 and joined in series the current through both of them is equal.
Heat Produced in the bulbs by their coils = i2Rt,
If the electric current and the time period are same for both the bulbs the heat produced by the coil is directly proportional to the resistance.
The energy consumed the two bulbs in them are in ratio of 1 : 2
