Though sir / ma' am you know that the formula of power is P = E / T .....from here u can simply conclude that power is directly proportional to Energy....
It means who have more power then it will also have more energy. ( here u can say that light energy ) ....
so come to the ques...here u come to know that three bulbs are arranged in parallel ...from the formula of power , p = V x I
p is directly proporional to I for who have power maximum then it also have current maximum..
from ques u came to know that the bulbs whom have more power is C so the light energy will be maximum and current will be maximum.. so the brightness will be max...in B light energy will be less than C and current will be less than C and brightness will be less than C.
if u come to A then it will be least in order....
So the order of brightness - C > B > A..
