In the circuit shown the cell will deliver maximum power to the network if the value of R is

A

`(2)/(3)Omega`

B

`(4)/(3)Omega`

C

`(1)/(3)Omega`

D

`(5)/(3)Omega`

Text Solution

Verified by Experts

The correct Answer is:
A
The cell will deliver maximum power to the network if `R_(eq)=r`
`implies(3R)/(2)=r`
`thereforeR=(2r)/(3)=(2)/(3)Omega`
