A battery of internal resistance 4 ohm is connected to the network of resistance as shown. In the order that the maximum power can be delivered to the network, the value of R in ohm should be:
Text Solution
Verified by ExpertsThe correct answer is:
B
The given circuit is that of a Wheatstone bridge.
The circuit is balanced one since,
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.
