In the circuit shown, the power dissipated in the resistor R is 1 W when only source ‘1’ is present and ‘2’ is replaced by short circuit. The power dissipated in the same resistor R is 4 W when only source '2’ is present and '1' is replaced by a short circuit When both the sources ‘1’ and ‘2’ are present, the power dissipated in R will be
  • a)
    5 W
  • b)
    4 W
  • c)
    3 W
  • d)
    1 W
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
In the circuit shown, the power dissipated in the resistor R is 1 W wh...
We have; 
or, 

or, 
When both the sources are present, net current through R will be
I = (I2 - I1
[as polarity of |V1| is reverse]
So, power loss in R is
