What is the power of bulb B1? … bulb B2?

the picture shows two level circuit with path one is point a and b in the middle is a light bulb B1
the second level path 2 shows lightbulb B2 and point c and d
and on the last level is point e and point f with a batter closer to point f.
point c and point e are not connected as there is an opening in the path
