Two bulbs of (40 W, 200 V) and (100 W, 200 V). Then correct relation for their resistance:

A

`R_(40) lt R_(100)`

B

`R_(4) gt R_(100)`

C

`R_(40) = R_(100)`

D

Non relation can be predicted

Text Solution

Verified by Experts

The correct Answer is:
B
`P = (V^(2))/(R ), P prop (1)/(R )`
i.e., `R_(40) gt R_(100)`
