Unformatted text preview: V an  = 120 V rms. Load 1: Z y = 150 ∠ 75 ° Ω Load 2: Z ∆ = 24 ∠10 ° Ω a) What are the phasor line currents? b) What is the line voltage? c) What is the total 3phase real power delivered by the source? d) What is the power factor of the combined loads? e) If a balanced threephase load is added to the circuit to correct the power factor to 0.91 lagging, what will this load be in its delta form. The real power delivered by the source and the voltage V an  may not change. f) What is the new line current magnitude?...
