A balanced \(\Delta\)-connected impedance load with \((12+j 9) \Omega\) per phase is supplied by a balanced three-phase \(60-\mathrm{Hz}, 208-\mathrm{V}\) source,

(a) Calculate the line current, the total real and reactive power absorbed by the load, the load power factor, and the apparent load power,

(b) Sketch a phasor diagram showing the line currents, the line-to-line source voltages, and the \(\Delta\)-load currents. Use \(V_{a b}\) as the reference.
