Two electic bulbs marked `25 W -220 V` and `100 W - 220 V` are connected in series to a 440 V supply. Which of the bulbs will fuse?

A

`25 W` bulbs

B

`100 W` bulbs

C

both bulbs

D

none

Text Solution

Verified by Experts

The correct Answer is:
A

`R=(V^(2))/(P) implies R_(25 W)gtR_(100W)`
When they are connected in series
`P=I^(2)R`
`P'_(25w)gtP'_(100 w)`
