The power dissipated in 3Omega resistor ...

The power dissipated in `3Omega` resistor in the circuits as shown in the figure is 2W. The power dissipated in `7Omega` resistor will be

A

14W

B

`14/3W`

C

`7/3W`

D

7W

Text Solution

Verified by Experts

The correct Answer is:
B
Use `P=i^2R`
`P_(3Omega) - (i/2)^2(3Omega)`
`(i^2)/(4) = 2/3`
`P_(7Omega) = (i/2)^2 xx7 = 2/3 xx7 = 24/3 W`
