In the circuit given below, the value of R required for the transfer of maximum power to the load having a resistance of 
is
Zero
Infinity
Since, variable resistance is in source side and load resistance is fixed.
So for maximum power to be transferred in a fixed load
resistance, the current should be maximum for maximum current to be delivered from 10V source variable resistance R should be zero.
R=0
Note: Maximum Power Transfer Theorem can only be applied when the load resistance is variable. Also, this can be derived by deriving the load power in terms of ‘R’ and then finding the maxima of the function but that would be a tedious process.
