Two identical electric lamps marked 500 ...

Two identical electric lamps marked `500 W`, `220 V` are connected in series and then joined to a `110 V` line. The power consumed by each lamp is

A

`(125)/(4)W`

B

`(25)/(4)W`

C

`(225)/(4)W`

D

`(325)/(4)W`

Text Solution

Verified by Experts

The correct Answer is:
A
`R_(1)=R_(2)=(V^(2))/(P)=R`
`i=(V)/(2R)`
`thereforeP=i^(2)R`
