.

A

`(4)/(9)`

B

`2`

C

`(8)/(3)`

D

`18`

Text Solution

Verified by Experts

The correct Answer is:
B



The given circuit is a balanced wheatstone's bridge Thus, no current will flow across 6 R of the side CD, the given circuit will now be equivalent to for maximum power net external resistance `=` Total internal resistance `R=2Omega`
