The value of the resistance R in figure ...

The value of the resistance `R` in figure is adjusted such that power dissipated in the `2Omega` resistor is maximum. Under this condition

A

`R=0`

B

`R=8 Omega`

C

power dissipated in the `2 Omega` resistor is `72 W`.

D

power dissipated in the `2 Omega` resistor is `8 W`.

Text Solution

Verified by Experts

The correct Answer is:
A, C
Power will be maximum in `2 Omega` when current through it is maximum. It happens when `R=0`
`I_(max)=6A`
`P_(2Omega)=(6)^(2)+2=72` watt
