Homework Answers
Please see There are two scanned sheets attached.
First of all Lets discuss Which bulb is brightest:
Since all bulbs are connected in series therefore current flowing through each bulb is same. Since Resistances of each bulb are different therefore the brightness is different because brightness depends on heat produced or power since heat produced is proportional to resistance hence greater the resistance greater is the brightness.
Resistance of first bulb is greater hence the first bulb of power 25 Watt will be brightest.
Now i am entering the answers in the boxes as asked. The explanations for those answers are attached on a scanned sheet.
