A battery of internal resistance 4Omega ...

A battery of internal resistance `4Omega` is connected to the network of resistance as shown . In order that the maximum power can be delivered to the network, the value of R in `Omega` should be
.

A

`(4)/(9)`

B

2

C

`(8)/(3)`

D

18

Text Solution

Verified by Experts

The correct Answer is:
B

(b) This is balanced wheat stone bridge
Form maximum power transfer theorem
Internal resistance = External resistance
`implies 4 = (3 R xx 6R)/(3R + 6 R) implies 4 = 2 R implies R = 2 Omega`
