For each set of voltages, state whether or not the voltages form a balanced three-phase set. If the set is balanced, state whether the phase sequence is positive or negative. If the set is not balanced, explain why. a () = 180 cos(377t 180 cos 377t V, 120°) V, = 180 cos(377t - 240°) V. a (q 180 sin(377t + 120°) V, 180 sin 377t V, %3D 180 sin(377t 120°) V. = "a () 400 sin(3771 + 210°) V, -400 sin 377t V, 400 cos(377t- 30°) V. 201 cos(2000r + 150°) V, 200 cos(2000t + 270°) V.
