In the interconnection of ideal soures shown in the figure, it is known that the 60V source is absorbing power. Which of the following can be the value of the current source I?
-
- 10A
- 13A
- 15A
- 18A
- 10A
Correct Option: A
The given figure 
Given that 60V source is absorbing power. It means current enters in the 60V source. Let the current entering in 60V source is IS.
KCL at point B, we get
I + Is = 12 …(i)
Now, this problem is further solved by applying Hit and trial method. From the given options, we conclude that only alternative (A) satisfy the equation (i).
