Question

The value of the resistance R in figure is adjusted such that power dissipated in the 2 capital omega resistor is maximum. Under this condition

  1. R = 0    
  2. R = 8 capital omega    
  3. power dissipated in the 2 capital omega resistor is 72 W    
  4. power dissipated in the 2 capital omega resistor is 8 W    

The correct answer is: R = 0
