In the following circuit, the magnitude of current I₁ is _____ A. Image

Question

G1 Physics · Accepted Answer

Applying junction equations to the two internal nodes gives node potentials x = 3 V and y = 0 V. The current in the right branch is I₁ = (y−0)/1 + (x−0)/2 = 0 + 3/2 = 1.5 A. The source key reports 2 A for this item; the question is preserved from the source paper.
