A battery of internal resistance `4 Omega` is connected to he network of resistances as shown in Fig. `7.40`. 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

For the maximum power.

External resistance= internal resistance `therefore 2R=4,R=2`
