Consider the figure shown below :

The power dissipated in resistor R is 1 W when only source (1) is acting alone and source (2) is replaced by its internal impedance. However it is 4 W when source (2) is acting alone and source (1) is replaced by its internal impedance. When both the sources are acting simultaneously, the possible value of the power dissipated tin R will be
