You can put this solution on YOUR website!
Let +R+ = the resistance of the bulbs filament
+500+=+220%5E2+%2F+R+
+R+=+48400%2F500+
+R+=+96.8+
There is +110%2F2+=+55+ volts across each bulb
+55%5E2%2F96.8+=+3025%2F96.8+
+3025+%2F96.8+=+31.25+
31.25 watts is generated by each bulb
hope I got it

Two electric bulbs each designed to operate with a 500 watts in 220 volt line are connected in series now they are connected with a 110 volt line what is the power generated by each bulb
---------------
P = E^2/R
R = E^2/P
R = 96.8 ohms
------------
In series, V across each bulb = 55 volts
----
P = 55^2/96.8
P = 31.25 watts
--------------
The bulbs don't generate any power, they consume it.
