When three identical bulbs are connected...

When three identical bulbs are connected in series. The consumed power is 10W. If they are now connected in pa rallel then the consumed power will be:-

A

30W

B

90W

C

`(10)/(3)W`

D

`270W`

Text Solution

Verified by Experts


`(1)/(P_(eq ))=(1)/(P_(1))+(1)/(P_(2))+(1)/(P_(3)) P_(eq)=P_(1)+P_(2)+P_(3)`
`rArr 10=(P)/(3) rArr P_(eq)=3P=3xx30=90` watt
