50w bulb has higher resistance.
how??
resistance is inversely proportional to power...
your answer is incorrect...
ok.
thanks for your comment.

First Case:
P=50W
R=1/50 ohms.
=0.02 ohms.
Second Case:
P=25W
R=1/25 ohms.
=0.04 ohms.
(Since resistance is inversely proportional to power).
Therefore,
Resistance is more in the second case.
