Question

In the given network V1=100∠0∘V_1 = 100\angle 0^\circ V, V2=100∠−120∘V_2 = 100\angle -120^\circ V, V3=100∠+120∘V_3 = 100\angle +120^\circ V. The phasor current ii (in Ampere) is
Three parallel branches between a left node and a right node. Top branch: source V1 in series with a capacitor marked -j1. Middle branch: source V2 in series with an inductor marked j1. Bottom branch: source V3 alone, with current i shown flowing left to right in this branch. No source polarity marks are printed.
