Consider the configuration shown in the figure which is a portion of a larger electrical network
For R = 1 Ω and currents i1 = 2 A, i4 = -1 A, i5 = -4 A. Which one of the following TRUE?
1
i6 = 5 A
2
i3 = -4 A
3
Data is sufficient to conclude that the supposed currents are impossible
4
Data is insufficient to identify the currents i2, i3, and i6
