Question: Find the complex power for the following cases: (a) P = 4 kW, pf = 0.86 (lagging) (b) S = 2 kVA, P = 1.6

Find the complex power for the following cases:
(a) P = 4 kW, pf = 0.86 (lagging)
(b) S = 2 kVA, P = 1.6 kW (capacitive)
(c) Vrms = 208 ∠ 20° V, Irms = 6.5 ∠ - 50° A
(d) Vrms = 120 ∠ 30° V, = 40 + 60 Ω
