Explanation:
Upon connecting both the bulbs in series the current through both of them will be 0.08 Amperes, which is more than the rated current of the 11 watt bulb (0.05 Amperes). Moreover the voltage drop across the 44 watt bulb is 88v while that across the 11 watt bulb is 352v which aga the rated voltage value of 220v.
