hope this is the right answer......

Answer 2

Answer:

the first lamp of 100 watts

Explanation:

current flowing in the series combination is same for all appliances. so,the resistance offered by the 500W Bulb will be more and less amount of current will pass through it

hence,heat produced by the 100W bulb will be more and it will glow brighter as compared to the 500W bulb
