3. There are two electric bulbs (i) marked 60 W, 220 V and (ii) marked 100 W, 220 V. Which one of the two has a higher resistance? On which the resistivity of a metallic wise depends.

p=v2r
60=(220)2r
_60_=r
48400
r=0.00123
same as mentoned above
__100__=r
48400
r=0.002
second will have more resistance
on temperature and nature of the material
