Power dissipated across the 8 Omega resi...

Power dissipated across the `8 Omega` resistor in the circuit shown here is `2 W` . The power dissipated in watt units across the `3 Omega` resistor

A

`2.0`

B

`1.0`

C

`0.5`

D

`3.0`

Text Solution

Verified by Experts

As voltage drop across `8Omega=sqrt(2xx8)`
`=4V(because P=(V^(2))/(R))`
Therefore voltage drop across `3Omega=3V`
[`because 4V` is divided in ratio of resistances between `1Omega` and `3Omega`]
Hence power dissipated in `3Omega=((3)^(2))/(3)=3` watt
